Quantum 8, 1508 (2024). https://doi.org/10.22331/q-2024-10-23-1508 The formalism of quantum theory over discrete systems is extended in two significant ways. First, quantum evolutions are generalized to act over entire network configurations, so that nodes may find […]
Galaxies have been merging into ever-bigger structures over the course of cosmic history. When galaxies merge, the supermassive black holes that sit in their centers must eventually merge, too, forming an even more gargantuan black […]
Quantum 8, 1507 (2024). https://doi.org/10.22331/q-2024-10-23-1507 Oblivious linear evaluation is a generalization of oblivious transfer, whereby two distrustful parties obliviously compute a linear function, $f (x) = ax + b$, i.e., each one provides their inputs […]
Insider Brief Nord Quantique announced partnerships with two major institutions to secure its supply chain for chip fabrication within the Northeast Semiconductor Manufacturing Corridor. The company partnered with the MiQro Innovation Collaborative Centre (C2MI) in […]
Nord Quantique, a quantum error correction company, announced two new partnerships to strengthen its semiconductor supply chain. These agreements are with the MiQro Innovation Collaborative Centre (C2MI) in Bromont, Quebec, and the New York Center […]
Quantum 8, 1506 (2024). https://doi.org/10.22331/q-2024-10-23-1506 In classical computing, error-correcting codes are well established and are ubiquitous both in theory and practical applications. For quantum computing, error-correction is essential as well, but harder to realize, coming […]
As quantum computing continues to develop, it introduces a threat to modern-day security standards. Quantum computing can’t break our widely used encryption methods today, but it threatens them with the possibility of decryption of saved […]
Quantum 8, 1505 (2024). https://doi.org/10.22331/q-2024-10-23-1505 We propose a simple, robust protocol to prepare a low-energy state of an arbitrary Hamiltonian on a quantum computer or programmable quantum simulator. The protocol is inspired by the adiabatic […]
Quantum 8, 1504 (2024). https://doi.org/10.22331/q-2024-10-23-1504 We develop quantum algorithms for pricing Asian and barrier options under the Heston model, a popular stochastic volatility model, and estimate their costs, in terms of T-count, T-depth and number […]
Insider Brief Google Quantum AI’s new LUCI error correction framework improves fault tolerance in quantum computers by dynamically adapting circuits to handle defective qubits and couplers, achieving a 36× reduction in logical error rates compared […]
