The race to build a fault-tolerant quantum computer is heating up, and Google, despite its early lead, is facing stiff competition. While Google has made significant strides with its surface code approach to quantum error correction, other players are exploring diverse strategies with promising results. This article delves into the complexities of quantum error correction, explores alternative approaches gaining traction, and analyzes the potential implications for the future of quantum computing. Quantum computing holds the promise of revolutionizing fields like medicine, materials science, and artificial intelligence by solving problems that are intractable for classical computers. However, qubits, the building blocks of quantum computers, are extremely fragile and prone to errors. This is where quantum error correction (QEC) comes in. QEC is a crucial technique to protect quantum information from noise, ensuring the reliability of quantum computations. Google has been a pioneer in this field, achieving a significant milestone in 2019 by demonstrating quantum supremacy – performing a calculation on a quantum computer that would be practically impossible for a classical computer. Their approach relies heavily on the surface code, a technique that distributes quantum information across a two-dimensional grid of qubits, making it more resilient to errors. However, the surface code, while robust, requires a large number of physical qubits to encode a single logical qubit – a qubit that is protected from errors. This overhead poses a significant challenge in scaling up quantum computers to tackle real-world problems. The Rise of Alternative Approaches Recognizing the limitations of the surface code, researchers are actively exploring alternative QEC codes that offer potential advantages in terms of efficiency and resource requirements. Some of the prominent contenders include: Companies like Quantinuum and IonQ are actively pursuing these alternative approaches, demonstrating their potential in experimental setups. Quantinuum, for instance, recently achieved a breakthrough with its trapped-ion quantum computer, demonstrating high-fidelity operations using a color code. IonQ, on the other hand, is leveraging its trapped-ion technology to explore the capabilities of LDPC codes. The Challenges and Opportunities Ahead While these alternative approaches offer promising avenues for quantum error correction, they also come with their own set of challenges. For instance, color codes, despite their higher threshold, can be more complex to implement. LDPC codes, while efficient, require careful optimization for quantum applications. Bosonic codes, being a relatively new approach, require further research and development to demonstrate their scalability and practicality. The exploration of these diverse approaches highlights the dynamic nature of the quantum computing field. There is no one-size-fits-all solution for quantum error correction, and the optimal approach may vary depending on the specific hardware platform and application. My Perspective: A Journey Through the Quantum Realm My fascination with quantum computing began during my graduate studies in physics. The counterintuitive nature of quantum mechanics, with its superposition and entanglement, captivated my imagination. I delved into the theoretical foundations of quantum error correction, exploring the intricate mathematics and code constructions that underpin this crucial field. Over the years, I’ve witnessed the remarkable progress in quantum computing, from the early demonstrations of basic quantum gates to the achievement of quantum supremacy. I’ve had the opportunity to interact with leading researchers in the field, attend conferences, and contribute to the development of quantum algorithms. The current exploration of alternative QEC codes excites me as it signifies a maturing field. It’s not just about achieving quantum supremacy anymore; it’s about building practical, fault-tolerant quantum computers that can solve real-world problems. The Road to Fault-Tolerant Quantum Computing The development of efficient and scalable quantum error correction is paramount to realizing the full potential of quantum computing. While Google’s surface code has paved the way, the emergence of alternative approaches is crucial for driving innovation and pushing the boundaries of this field. The competition in quantum error correction is ultimately beneficial for the advancement of quantum computing. It fosters collaboration, encourages the exploration of diverse ideas, and accelerates the development of fault-tolerant quantum computers that will revolutionize various industries. This is an exciting time to be involved in quantum computing. We are witnessing the birth of a new technological era, and quantum error correction is at the forefront of this revolution.Donald Trump Jr has emerged as the most influential Trump family member in the transition as the president-elect builds the most controversial cabinet in modern US history, according to a half dozen sources with knowledge of his role, elevating inexperienced loyalists over more qualified candidates for top positions in his administration. or signup to continue reading Trump, who fiercely prizes loyalty, has long relied on family members for political advice, but which relative has his ear is known to vary. This time, it is Don Jr who has helped cabinet contenders sink or rise to the fore - from championing Senator JD Vance as Trump's running mate to blocking former Secretary of State Mike Pompeo from joining the cabinet, according to the sources, who include donors, personal friends and political allies. Don Jr is due to join conservative venture capital fund 1789 Capital, although one of the sources said he will continue to host his politics-focused podcast and support candidates that espouse Trump's brand of politics. He will provide advice to his father in the White House, the source added, although they cautioned that Don Jr was unlikely to be involved in day-to-day deliberations. Don Jr and the Trump-Vance transition team did not respond to a request for comment. In addition to ensuring candidates are loyal to his father, Don Jr typically seeks out contenders who embrace an anti-establishment worldview, including protectionist economic policies, and a reduction in military interventions and overseas aid, according to a handful of the sources and Don Jr's own comments on social media site X and in public. Two of the candidates Don Jr championed may face a rocky confirmation process in the Senate: Robert F Kennedy Jr, who Trump plans to nominate as the top US health official, and Tulsi Gabbard, who Trump plans to nominate as intelligence chief. Kennedy is an environmental activist who has spread misinformation on vaccines. Gabbard, a former Democratic congresswoman, implied that Russian President Vladimir Putin had valid grounds for invading Ukraine and stirred controversy when she met Syrian President Bashar al-Assad in the midst of his bloody crackdown on dissidents in 2017. Don Jr was also instrumental in lobbying his father to pick his close friend Vance as Trump's running mate - a win that has given him extra political capital as an adviser during the transition, one of the sources added. "The reality this time is we actually know what we're doing," Don Jr told Fox News earlier this month. "And it's about surrounding my father with people who are both competent and loyal." Trump's daughter Ivanka and her husband Jared Kushner were prominent in his 2016 presidential campaign, the subsequent transition and throughout his first term. This time, they are far less active, although Kushner, formerly Trump's senior adviser who focused on the Middle East, told Reuters that he is briefing real estate investor Steve Witkoff on his new job as special envoy to the region. "I have been working with Witkoff to get him up to speed on Trump's past efforts," Kushner said through a spokesperson. A half-dozen sources close to Kushner said they expect him to be involved in Middle Eastern policy in an unofficial capacity, with the goal of normalising relations between Israel and Saudi Arabia under an expansion of the 2020 Abraham Accords. Kushner helped broker the accords, a series of normalisation agreements between Israel and Arab nations. Kushner, Ivanka and sibling Eric Trump, who runs the Trump Organization business, do not plan to join the new administration, according to their representatives as well as sources. One source close to the transition said Trump does not appear to need his family for advice as much as in the past because of aides like Susie Wiles, who helped to run the most disciplined of his election campaigns to date. Trump has named Wiles as his chief of staff, a powerful position in Washington. "Stuff is really buttoned down," the source said of Trump's current team. "He may not need the family this time like he used to." Advertisement Sign up for our newsletter to stay up to date. We care about the protection of your data. Read our . Advertisement
After less than a year in the business, Tempe Eats, a food hall concept in Tempe, is shutting down. The establishment, which debuted in February of this year and is situated at the southeast corner of Mill and Southern avenues, is discontinuing its operations on January 7, as per Phoenix Business Journal . It once boasted a selection of eight unique eateries that offered an array of dishes ranging from pasta and sushi to burgers and BBQ. The food hall was known for its adoption of technology enabling patrons to place orders from any of the on-site restaurants in a single transaction and have their selections delivered straight to their table. It also featured a drive-thru window and a few bar areas. Despite these amenities, the tenure of the concept was brief. According to information acquired by KTAR News , the space currently housing Tempe Eats isn't going to waste, however, as plans are underway to transform it into a venue for events and private parties. Teresa Nguyen, the owner of Tempe Eats, mentioned in a statement , "We're excited to focus on creating memorable experiences for special occasions." Throughout its short-lived presence, Tempe Eats hosted several community events, from themed nights featuring Latin and Country music to fundraisers and live performances. With a vision for the future, Nguyen sees potential in the location, anticipating that it will serve as a sought-after spot for private events and celebrations, as well as a place for community gatherings. The Southern + Mill shopping center, where Tempe Eats is located, will witness this transition. The center is known for its anchor, LA Fitness, and includes a diverse mix of tenants like Venezia's Pizza.Nigel Farage demands Kemi Badenoch appear on GB News to apologise for accusing him of lying about his party's membership By DAVID CHURCHILL CHIEF POLITICAL CORRESPONDENT Published: 21:38 GMT, 29 December 2024 | Updated: 21:39 GMT, 29 December 2024 e-mail View comments Nigel Farage last night appeared to threaten Kemi Badenoch with legal action unless she apologises for accusing him of lying about Reform's membership figures. The Reform UK leader's warning came in response to the Tory chief publicly accusing him of lying about the numbers joining his party after he claimed on Boxing Day that its membership had overtaken the Conservative Party 's. Just before midday on Thursday, Reform said it had hit 131,680 supporters – the same as the last-known figure for the Tories. The Right-wing party then provocatively projected an image of the total on Tory HQ in London . Asked if he could sue for libel over what he described as 'accusations of fraud and dishonesty', Mr Farage said: 'I'm going to take some action in the next couple of days and I've got to decide exactly what it is. 'But I'm certainly not going to take it lying down. It's an absolutely outrageous thing for her to have said. Nigel Farage appeared to threaten Kemi Badenoch with legal action unless she apologises for accusing him of lying about Reform's membership figures 'Now I know she's got a very bad temper, I know she's well known for lashing out at people. I'm not at all happy and I'm going to take some action. 'Once we've fully disproved this, she's going to find life a lot more difficult and bitterly regret putting this out on Boxing Day afternoon.' Mr Farage later appeared to row back over the threat, telling the Press Association: 'I've just said that unless I get an apology, I will take some action. I haven't said whether it's legal or anything. Kemi Badenoch publicly accused Farage of lying about the numbers joining his party after he claimed on Boxing Day that its membership had overtaken the Conservative Party's 'All I've said is I want an apology. If I don't get an apology, I will take action.' His party claims its membership figures, shown via a live ticker on its website, are based on verified data which is logged in real time through a third-party website. But it has not ruled out the possibility some could be based abroad and not UK residents. The Tories last night doubled down on Mrs Badenoch's position. A party source said: 'Farage is clearly rattled that his Boxing Day publicity stunt is facing serious questions over hundreds of 'members' seemingly joining in the middle of the night.'
