Quantum 10, 2140 (2026). https://doi.org/10.22331/q-2026-06-15-2140 Phase estimation, due to Kitaev [17], is one of the most fundamental subroutines in quantum computing. In the basic scenario, one is given black-box access to a unitary $U$, and […]
Insider Brief Quantonation has appointed Magnus Bengtsson and Elizabeth Ruetsch as Venture Partners to support the commercialization and scaling of its quantum and deep-tech portfolio companies. Bengtsson brings leadership experience from Coherent Corp., while Ruetsch […]
Quantum 10, 2139 (2026). https://doi.org/10.22331/q-2026-06-15-2139 Nonlocality is an essential concept that distinguishes quantum from classical models and has been extensively studied in systems of qubits. For higher-dimensional systems, certain results for their two-level counterpart, like […]
Insider Brief The CHIRON project has launched in Germany to develop a scalable quantum communication infrastructure based on entanglement-enabled Quantum Key Distribution (QKD). The consortium will demonstrate quantum-secure networking through testbeds in Berlin and Thuringia, […]
Quantum 10, 2138 (2026). https://doi.org/10.22331/q-2026-06-15-2138 This work investigates whether quantum walks on simplicial complexes exhibit quantum advantages. We introduce a novel quantum walk that encodes the combinatorial Laplacian, a key object reflecting the topology of […]
A team of U.S. researchers has designed a passive quantum error correction technique that enables qubits to correct their own errors. Demonstrated by Shruti Shirol and colleagues at the University of Massachusetts Amherst, the protocol […]
