A team from University of Science and Technology of China (USTC) experimentally implemented a scalable quantum state verification on two-qubit and four-qubit entangled states with nonadaptive local measurements. The initialization of a quantum system into
A team of researchers at the University of Toronto has found a way to measure how long quantum tunneling takes to happen. One factor of quantum tunneling that has been debated by physicists over the
Services Industriels de Genève (SIG), Geneva’s utility company (Switzerland), ID Quantique (IDQ), one of the leading company in quantum-safe security solutions, and ADVA, a provider in secure open optical networking solutions, announced today the implementation
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
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
