How A Novel Radio Frequency Control System Enhances Quantum Computers

A team of physicists and engineers at Lawrence Berkeley National Laboratory (Berkeley Lab) successfully demonstrated the feasibility of low-cost and high-performance radio frequency modules for qubit controls at room temperature. They built a series of compact radio frequency (RF) modules that mix signals to improve the reliability of control systems for superconducting quantum processors. Their tests proved that using modular design methods reduces the cost and size of traditional RF control systems while still delivering superior or comparable performance levels to those commercially available.

Orbiting Now! Quantum Communications Experiment, CAPSat, to Test Quantum Communications

A quantum communications experiment was launched into low orbit around Earth from the International Space Station (ISS). A collaborative experiment of the University of Illinois Urbana-Champaign and the University of Waterloo, CAPSat (Cool Annealing Payload Satellite) contains single-photon detectors, which can be used as receivers for unhackable quantum communications.

BT and Toshiba to Build World’s First Quantum-Secured Commercial Metro Network

BT and Toshiba have announced plans to build the world’s first commercially available, quantum-secured metro network in London. The network will connect sites in London’s West End, the City and the M4 corridor, providing data services secured using quantum key distribution (QKD) and post-quantum cryptography (PQC) encryption.

Archer Materials Validates & Demonstrates Qubit Coherence at Room Temperature, in Non-Vacuum Environment

For the first time, Archer Materials validated that the qubits’ quantum coherence properties‡ are preserved under an inert atmosphere. Quantum coherence is the fundamental requirement for quantum logic operations that are the basis of any quantum computing qubit processor hardware. For potential integration and use of qubit materials in practical chip devices, it is significant to demonstrate and validate qubit robustness at room temperature and under atmospheric environments other than that of air or vacuum.
