The newly developed qubits are based on so-called holes (red) whose spin (arrow) in one or the other direction stores the information. They are arranged in an architecture based on silicon transistors. (Illustration: NCCR Spin)

Hot spin qubits in silicon transistors

A research group at the University of Basel, working with the IBM Research Laboratory, has made a breakthrough in qubits scalability. In classic computers, the solution to the scalability problem lay in silicon chips, which […]

New world record for qubit storage

A UNIGE team in Geneva, Switzerland, has succeeded in storing a quantum bit for 20 milliseconds. A duration that had never before been achieved by a solid-state quantum memory. Long-duration quantum memories for photonic qubits […]

New world record for qubit storage

Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks. There […]
