Scientists at Centre for Quantum Computation and Communication Technology (CQC2T) have demonstrated coherence times 10,000 times longer than previously recorded for spin-orbit qubits. Coherence time is the duration of time that a spin-orbit qubit in
Quantum magnetometry aims to measure the magnetic field with the highest precision. Although estimation of one component of a magnetic field has been well studied over many decades, the highest precision that can be achieved
A new device that relies on flowing clouds of ultracold atoms promises potential tests of the intersection between the weirdness of the quantum world and the familiarity of the macroscopic world we experience every day.
Researchers at Columbia Engineering and Montana State University have reported that they have found that placing sufficient strain in a 2-D material—tungsten diselenide (WSe2)—creates localized states that can yield single-photon emitters. Using sophisticated optical microscopy
Researchers at MIT have designed a quantum light squeezer that reduces quantum noise in an incoming laser beam by 15 percent. It is the first system of its kind to work at room temperature, making it amenable
Distributed quantum information processing is based on the transmission of quantum data over lossy channels between quantum processing nodes. These nodes may be separated by a few microns or on planetary scale distances, but transmission
ITMO University researchers have developed a Quantum Key Distribution (QKD) system with coherent detection based on subcarrier wave quantum key distribution protocol. This is a continuous-variable quantum key distribution protocol using multimode coherent states generated
A new machine learning framework could pave the way for small, mobile quantum networks. Researchers from the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory and Tulane University combined machine learning with Quantum Information Science
PQShield, a UK post-quantum cryptography startup, today comes out of stealth mode with the announcement of a £5.5m seed funding raise, and news that it has won Bosch as its first customer. Originating from the
Researchers at MIT have developed a process to manufacture and integrate “artificial atoms,” created by atomic-scale defects in microscopically thin slices of diamond, with photonics circuitry, producing the largest quantum chip of its type. The
