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 […]
Insider Brief A new report from the Special Competitive Studies Project finds that the United States maintains a slight overall lead over China in quantum technologies, but warns that China’s coordinated national strategy is steadily […]
Quantum 10, 2137 (2026). https://doi.org/10.22331/q-2026-06-15-2137 Simulations of quantum systems with Hamiltonian classical stochastic noise can be challenging when the noise exhibits temporal correlations over a multitude of time scales, such as for $1/f$ noise in […]
Quantum 10, 2136 (2026). https://doi.org/10.22331/q-2026-06-15-2136 We introduce a non-equilibrium version of the Caldeira-Leggett model in which a quantum particle is strongly coupled to a set of engineered reservoirs. The reservoirs are composed by collections of […]
Insider Brief QuEra announced Libra, a fault-tolerant quantum computer planned for 2028, alongside an expanded multi-year collaboration with AWS to make the system available through Amazon Braket. Libra is designed to deliver more than 256 […]
Insider Brief Atom Computing and Phasecraft have signed a memorandum of understanding to explore how application-focused algorithms can benchmark progress toward utility-scale quantum computing. The collaboration will adapt Phasecraft’s quantum algorithms to Atom Computing’s neutral-atom […]
