Classiq, a quantum software company, has announced new investments in its Series C funding round from SoftBank Vision Fund 2 and CDP Venture Capital, Italy’s largest venture capital operator. The investment expands Classiq’s previously announced […]
Insider Brief Zero Point Cryogenics has received a U.S. patent for a new cryogenic system that enables continuous cooling to 500 millikelvin without requiring large volumes of helium-3. The system, called the Phase Separation Refrigerator, […]
Quantum computers, devices that can perform computations relying on the principles of quantum mechanics, are expected to outperform classical computers on some types of optimization and processing tasks. While physicists and engineers have introduced various […]
Quantum 9, 1817 (2025). https://doi.org/10.22331/q-2025-07-30-1817 We propose several algorithms for learning unitary operators from quantum statistical queries with respect to their Choi-Jamiolkowski state. Quantum statistical queries capture the capabilities of a learner with limited quantum […]
Several quantum companies are discussing a strategy for building quantum computers that leverages the trillions of dollars in investments made by semiconductor manufacturers over the past 75 years. To dig deeper, we decided to speak […]
Podcaster Follows His Curiosity to Explore Quantum Overview Yuval Boger, also known as The Superposition Guy, has been podcasting for more than 15 years and discussing technology ranging from wireless charging to VR headsets. The […]
Used as a versatile material in industry and health care, magnesium oxide may also be a good candidate for quantum technologies. Research led by the U.S. Department of Energy’s (DOE) Argonne National Laboratory and published […]
Deep beneath the Swiss-French border, the Large Hadron Collider unleashes staggering amounts of energy and radiation—enough to fry most electronics. Enter a team of Columbia engineers, who built ultra-rugged, radiation-resistant chips that now play a […]
Quantum 9, 1816 (2025). https://doi.org/10.22331/q-2025-07-29-1816 We introduce “dual-unitary shadow tomography” (DUST), a classical shadow tomography protocol based on dual-unitary brick-wall circuits. To quantify the performance of DUST, we study operator spreading and Pauli weight dynamics […]
Quantum 9, 1815 (2025). https://doi.org/10.22331/q-2025-07-29-1815 In the paradigmatic example of quantum measurements, whenever one measures a system which starts in a superposition of two states of a conserved quantity, it jumps to one of the […]
