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: Last year, IBM demonstrated that quantum computers had entered the era of utility, where they are now capable of running quantum circuits better than classical computers can. Over the next few years, they expect to find speedups over classical computing and extract business value from these systems.

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

18 Mar 2024: The researchers have successfully created a large-scale array of optical tweezers that can trap over 6,100 neutral atoms across 12,000 sites, achieving new heights in several critical performance metrics for this technology. They demonstrated: A coherence time of 12.6 seconds, a record for hyperfine qubits in an optical tweezer array. Trapping lifetimes close to 23 minutes in a room-temperature apparatus, enabling record-high Imaging survival of 99.98952% in combination with an imaging fidelity of over 99.

NVIDIA has more than 160 partners in its quantum computing ecosystem. Leading cloud service providers are integrating Quantum Cloud into their offerings, including Google Cloud, Microsoft Azure and Oracle Cloud To learn more about NVIDIA Quantum Cloud, watch the GTC keynote from Jensen Huang, and register for GTC for free to attend sessions from NVIDIA and industry leaders through March 21.

11 Mar 2024: Tuta Mail has announced TutaCrypt, a new post-quantum encryption protocol to secure communications from powerful and anticipated decryption attacks. TutaCrypt combines CRYSTALS-Kyber (Also used in QRL Zond) for post-quantum key encapsulation and X25519 for the Elliptic-Curve-Diffie-Hellmann key exchange.

11 Mar 2024: JILA breakthrough in integrating artificial atoms with photonic circuits advances quantum computing efficiency and scalability. Historically, there have been problems with integrating artificial atoms with photonic circuits. This is because creating the artificial atoms (where atoms are knocked out of a diamond crystal) is a very random process, leading to random placement of the artificial atoms, random number of artificial atoms at each location, and random color each artificial atom emits.
