Quantum error correction (QEC) is a hot topic these days so GQI has created a 21 page document that provides an in-depth analysis of the current state of the art in quantum error correction research. […]
Project Eleven (P11) has announced the QDay Prize, an open competition offering a reward of one Bitcoin (current value about $85,000) for demonstrating the ability to break elliptic curve cryptography (ECC) using Shor’s algorithm on […]
Insider Brief Researchers demonstrated that quantum strategies can outperform classical ones in trading scenarios by experimentally verifying quantum game theory on a real quantum computer. By entangling qubits and using a quantum logic gate as […]
Insider Brief The Trump administration is embracing quantum technology as a strategic tool for national security, infrastructure protection, and space exploration, despite tensions with scientific agencies. Federal leaders acknowledge the importance of international alliances, talent […]
A team of researchers has developed a new way to control light interactions using a specially engineered structure called a 3D photonic-crystal cavity that could enable transformative advancements in quantum computing, quantum communication and other […]
Quantum 9, 1718 (2025). https://doi.org/10.22331/q-2025-04-18-1718 We work out the general theory of one-parameter families of partial entanglement properties and the resulting entanglement depth-like quantities. Special cases of these are the depth of partitionability, the depth […]
Quantum 9, 1717 (2025). https://doi.org/10.22331/q-2025-04-18-1717 In unitary property testing a quantum algorithm, also known as a tester, is given query access to a black-box unitary and has to decide whether it satisfies some property. We […]
It started with a bet. In the late 1980s, at a conference in Lausanne, the mathematicians Noga Alon and Peter Sarnak got into a friendly debate. Both were studying collections of nodes and edges called […]
Quantum 9, 1716 (2025). https://doi.org/10.22331/q-2025-04-18-1716 $mathcal{PT}$-symmetric systems have garnered significant attention due to their unconventional properties. Despite the growing interest, there remains an ongoing debate about whether these systems outperform their Hermitian counterparts in practical […]
Quantum 9, 1715 (2025). https://doi.org/10.22331/q-2025-04-18-1715 We study the geodesics on the manifold of mixed quantum states for the Bures metric. It is shown that these geodesics correspond to physical non-Markovian evolutions of the system coupled […]
