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 […]

Perfect photons feed new quantum processor

A quantum processor working with photons developed at the University of Twente becomes an ever stronger ‘toolbox’ for doing experiments. The latest version not only has more inputs and outputs, it can also be fed […]

Sensing light

Physicists of the attoworld-team at Ludwig-Maximilians-Universität have uncovered what happens during the sampling of a light field. This helped them increase the sensitivity of the measurement by up to one order of magnitude.
