Research teams from USTC have realized a high-performance single-photon source with an efficiency beyond the scalable linear optical quantum computing loss tolerance threshold for the first time. Led by Prof. Pan Jianwei, Lu Chaoyang and […]
For the better part of a century, the quantum objects known as quasiparticles have been all dressed up with nowhere to go. But that may change, now that a Yale-led team of physicists has shown […]
Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that teleology is a remnant of antiquated ways of thinking about causation, and […]
For many years, physics studies focused on two main types of magnetism, namely ferromagnetism and antiferromagnetism. The first type entails the alignment of electron spins in the same direction, while the latter entails the alignment […]
Humans tend to put our own intelligence on a pedestal. Our brains can do math, employ logic, explore abstractions and think critically. But we can’t claim a monopoly on thought. Among a variety of nonhuman […]
Insider Brief: Bosch has formed a joint venture with Element Six to commercialize quantum sensors, with Bosch leading operations and Element Six holding a 25% stake. The sensors use synthetic diamonds with nitrogen-vacancy centers to […]
Quantum 9, 1694 (2025). https://doi.org/10.22331/q-2025-04-07-1694 The accurate and efficient energy estimation of quantum Hamiltonians consisting of Pauli observables is an essential task in modern quantum computing. We introduce a Resource-Optimized Grouping Shadow (ROGS) algorithm, which […]
Quantum 9, 1693 (2025). https://doi.org/10.22331/q-2025-04-07-1693 Spatially-coupled (SC) codes is a class of convolutional LDPC codes that has been well investigated in classical coding theory thanks to their high performance and compatibility with low-latency decoders. We […]
Insider Brief: Osney Capital launches a £50 million (over $64 million) fund to invest in seed-stage cybersecurity startups across the UK and Canada, establishing a Calgary office to support its cross-border strategy. Calgary’s growing quantum […]
Quantum 9, 1692 (2025). https://doi.org/10.22331/q-2025-04-07-1692 The dynamics of monitored systems can exhibit a measurement-induced phase transition (MIPT) between entangling and disentangling phases, tuned by the measurement rate. When the dynamics obeys a continuous symmetry, the […]
