19 May 2024: Mathematician Massimiliano Sala warns that current encryption methods won’t protect blockchain systems from future quantum computers, urging the development of quantum-resistant cryptosystems.

17 May 2024: Researchers have developed a secure method called “blind quantum computing” that allows PCs to connect to quantum computers over the internet using fiber-optic cables and quantum memory, potentially making advanced quantum computing more accessible.

17 May 2024: Researchers at the University of Bristol have created the world’s smallest quantum light detector on a silicon chip, significantly advancing the miniaturization of quantum technology. This detector, which is thinner than a human hair, operates ten times faster than previous models and is integrated onto a single chip, reducing its footprint by 50 times. The innovation could pave the way for more scalable and practical quantum computers, which currently require large spaces and extremely low temperatures to function.

12 May 2024: NVIDIA has announced the integration of its open-source CUDA-Q platform to accelerate quantum computing research at supercomputing centers in Germany, Japan, and Poland. These centers will utilize Quantum Processing Units (QPUs) within their NVIDIA-accelerated high-performance computing systems to enhance quantum research capabilities. Germany’s Jülich Supercomputing Centre will complement its JUPITER supercomputer with a QPU from IQM Quantum Computers, while Japan’s AIST will use a QuEra QPU in its ABCI-Q supercomputer to advance AI, energy, and biology applications.

07 May 2024: Scientists have developed an ultra-pure form of silicon, dubbed silicon-28 (Si-28), that could serve as the basis for “silicon-spin qubits” in quantum computers, according to a study published in Nature Communications Materials. Quantum bits or qubits, unlike classical computer bits, can exist in a superposition of states, potentially making quantum computers more powerful than today’s fastest supercomputers. However, qubits are highly susceptible to interference and require cooling to near absolute zero.

22 Apr 2024: Researchers in China have developed a quantum light source using gallium nitride (GaN), a common semiconductor traditionally used in blue light-emitting diodes. This development is seen as a significant step towards creating functional quantum chips. The GaN-based quantum light source can generate pairs of entangled light particles, which are essential for transmitting information within quantum systems. Additionally, this device offers a broader wavelength range than existing quantum light sources. The researchers suggest that this advancement could lead to more efficient and easily integrated quantum chips, with vast potential applications in quantum computing.

12 Apr 2024: PsiQuantum, a Palo Alto-based startup, anticipates delivering its first commercial quantum computing system in under six years, which is faster than many expert estimates. This accelerated timeline is due to research advancements and strategic partnerships, notably with chip manufacturer GlobalFoundries and the U.S. Department of Energy. The latter collaboration allows PsiQuantum to use facilities at the SLAC National Accelerator Laboratory to design crucial cryogenic quantum modules. Valued at $3.15 billion with $700 million in funding, the company aims to assemble multiple quantum modules into a data center-like configuration, targeting around 1 million quantum bits (qubits) for practical applications.

05 Apr 2024: A team of computer engineers from quantum computer maker Quantinuum, working with computer scientists from Microsoft, has found a way to greatly reduce errors when running experiments on a quantum computer. The combined group has published a paper describing their work and results on the arXiv preprint server.

28 Mar 2024: Singtel will partner with Cisco, Fortinet and Nokia to provide quantum security solutions to enterprises through its Quantum Safe Network (QSN).

27 Mar 2024: While gen AI has captured the attention of virtually every CIO, quantum computing is priming to take center stage.
