20 Apr 2023: Cornell researchers have recently taken a step toward fault-tolerant quantum computing: they constructed a simple model containing exotic particles called non-Abelian anyons, compact and practical enough to run on modern quantum hardware. Realizing these particles, which can only exist in two dimensions, is a move towards implementing it in the real world. Eun-Ah Kim, professor of physics (A&S), “With this 10-qubit system, we were able to encode multiple non-Abelian anyons, and therefore multiple logical information-carrying qubits, and a precise recipe for what the experimentalists need to do every step of the way.

20 Apr 2023: India’s government has signed off on a ₹6003.65 crore ($730 million) plan to make the nation a quantum computing and communications power by the year 2031.

03 Apr 2023: Due to the deep interconnectivity of the financial sector and the vulnerability of equity and credit markets, the US financial system is at risk of a quantum-enabled cyberattack. The consequences of such an attack could be catastrophic for the US and global economy, potentially surpassing the impact of the 2008 financial crisis or the Great Depression.

28 Mar 2023: Riken’s first homegrown quantum computer could transform auto, finance, chemical, and pharmaceutical industries. The government and Riken plan to connect an over-100-qubit quantum computer to the Fugaku supercomputer in fiscal 2025. Fujitsu plans to finish a 64-qubit quantum computer in fiscal 2023 and 1,000 in 2026. Fujitsu will collaborate with Fujifilm and Tokyo Electron, while Riken will research Japanese businesses and universities. Quantum computing may help develop new materials like electric-vehicle batteries and artificial photosynthesis.

21 Mar 2023: With new software and hardware, Nvidia Corp (NVDA.O), which powers most AI, is positioning itself as a quantum computing leader. Nvidia unveiled CUDA Quantum, a platform for building quantum algorithms in C++ and python, at GTC on Tuesday. The programme would run the algorithm on quantum and classical computers to find the most efficient solution. Nvidia’s DGX Quantum hardware system connects quantum and classical computers. It is unclear when quantum computers could perform some calculations millions of times faster than the fastest supercomputer.

13 Mar 2023: The UK government is investing £2.5bn in quantum computing to keep the UK competitive in one of the world’s fastest-moving fields. The National Quantum Computing Centre will play a leading role in the expanded programme. The UK has the most quantum start-ups in Europe, with a new government programme to boost homegrown companies and address the shortage of qualified workers.

15 Dec 2022: SpinQ Technology, a Chinese company based in Shenzhen, has introduced three new portable quantum computing products aimed at educational use: the Gemini Mini, the Gemini, and the Triangulum. These devices are designed to make physical quantum computing more accessible, though they feature limited capabilities with qubit counts maxing out at three. Utilizing nuclear magnetic resonance (NMR) spin qubits, these systems operate at room temperature but face significant scalability issues and lack key quantum features like entanglement.

11 Dec 2022: Amazon Web Services (AWS) is hosting Aquila by QuEra, the first publicly available neutral atom quantum computer on Amazon Braket. For Aquila’s 256-bit neutral-atom quantum processor, Qubits are laser developed in a vacuum chamber, where a cloud of rubidium atoms is trapped by magnetic fields. Laser light then is used to capture individual atoms of that cloud, holding them like tweezers, and constraining their motion so that they are effectively chilled to close to absolute zero.

01 Dec 2022: Quantum information traveled across a quantum system in what could be understood as traversing a wormhole. A wormhole is a bridge between two remote spacetime regions. This experiment performed on the Sycamore quantum processor device at Google opens the doors to future experiments with quantum computers. The Sycamore 53-qubit quantum processor allows researchers to send signals “through the wormhole”. This opens up the possibility of future quantum gravity experiments with larger quantum computers.

30 Nov 2022: Researchers used Google’s Sycamore quantum computer to simulate a holographic wormhole, demonstrating how information might travel through it via quantum teleportation, which could aid in understanding and developing a theory of quantum gravity.
