Quantum 10, 2038 (2026). https://doi.org/10.22331/q-2026-03-23-2038 Quantum walks in general graphs, or more specifically scattering on graphs, encompass enough complexity to perform universal quantum computation. Any given quantum circuit can be broken down into single- and […]
Quantum 10, 2037 (2026). https://doi.org/10.22331/q-2026-03-23-2037 In recent years, quantum key distribution (QKD) has evolved from a scientific research field to a commercially available security solution, supported by mathematically formulated security proofs. However, since the knowledge […]
Quantum 10, 2036 (2026). https://doi.org/10.22331/q-2026-03-23-2036 We introduce an efficient method to quantify nonstabilizerness in fermionic Gaussian states, overcoming the long-standing challenge posed by their extensive entanglement. Using a perfect sampling scheme based on an underlying […]
Scientists in Australia have demonstrated a prototype quantum battery that could revolutionize energy storage. By harnessing quantum effects, it can absorb energy in a rapid “super absorption” event, enabling much faster charging than conventional batteries. […]
Scientists have created a new kind of time crystal using sound waves to levitate tiny beads in mid-air. These particles interact in a one-sided, unbalanced way, breaking the usual rules of motion and creating a […]
SEEQC has published a study in Nature Electronics documenting the operation of a full-stack quantum computing system with integrated digital superconducting logic at 10 mK. The research demonstrates an “active” quantum processing unit (PPU) where […]
TUMCREATE, the research arm of the Technical University of Munich (TUM) funded by the National Research Foundation (NRF) Singapore, has announced its leadership role in the QUASAR-CREATE program. This three-and-a-half-year initiative, “Quantum Security and Resilience […]
BTQ Technologies has announced the deployment of Bitcoin Quantum testnet v0.3.0, which includes the functional implementation of Bitcoin Improvement Proposal (BIP) 360. This proposal, titled Pay-to-Merkle-Root (P2MR), provides a quantum-resistant output type and was added […]
The Canadian government has announced a $900 million investment through the National Research Council of Canada (NRC) to implement a long-term Defence Industrial Strategy. This initiative focuses on the development and commercialization of dual-use technologies, […]
A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex topological structures. Researchers found these hidden patterns reach up to 48 dimensions, offering a vast new “alphabet” for encoding […]
