Pasqal and Eleven Ventures announced an agreement to establish a commercial joint venture to deploy and scale Pasqal’s quantum computing systems across the Kingdom of Saudi Arabia and the broader MENA region, coinciding with the State Visit of the Kingdom of Saudi Arabia to France on August 24, 2026. The venture is designed to advance the Kingdom’s Vision 2030 ambitions in artificial intelligence…

A tiny chip that produces a precisely organized “rainbow” of light could help enable faster, higher-capacity 6G communications and more precise timing for quantum technologies. A microchip about the size of a grain of rice can generate a carefully ordered spectrum of light and convert it into multiple high-frequency electromagnetic signals called millimeter waves. Physicists [...]

Following a Series A investment round which raised $40m, optical interconnect startup, Quintessent, is sampling its single-chip quantum dot-based DWDM (dense wavelength division multiplexing) comb laser. Described as a new […] The post Quintessent begins sampling single-chip DWDM comb laser appeared first on Electronics Weekly .

Researchers have created a tiny chip that produces a stable “rainbow” of light capable of generating multiple high-frequency signals at once, potentially boosting the speed and capacity of future 6G networks. Its extreme precision could also make it valuable for quantum timing, navigation, radar, and even space-based technologies.

Quantum computing isn’t waiting to become useful—its practical hybrid phase is already underway.

Diraq is an Australian quantum computing company that builds spin qubits in silicon using the same kind of manufacturing that produces conventional computer chips.

Infleqtion builds neutral-atom quantum computers and sensors from Louisville, Colorado, and listed on the NYSE as INFQ in February 2026. Its history, its Sqale roadmap and what the filings actually show.

Scientists have developed a tiny “rainbow on a chip” that can produce multiple extremely precise high-frequency signals, a technology that could eventually support faster 6G communications, advanced radar and highly accurate quantum timing systems. Researchers led by Loughborough University created the system using a microchip about the size of a grain of rice. The chip […] The post ‘Rainbow on a…

Google Quantum AI researchers have determined that breaking the core cryptography of various cryptocurrencies, secured by the secp256k1 curve, may require as few as 1200 logical qubits and 90 million Toffoli gates, a significantly lower threshold than previously understood.

New Google research shows a potential Bitcoin vulnerability, estimating a quantum computer could break its cryptography with as few as 1200 logical qubits.
