Physicists have found a simple and effective way to skip over an energy level in a three-state system, potentially leading to increased quantum computational power with fewer qubits. Click to rate this post! [Total: 0 […]
When it comes to layered quantum materials, current understanding only scratches the surface; so demonstrates a new study from the Paul Scherrer Institute PSI. Using advanced X-ray spectroscopy at the Swiss Light Source SLS, researchers […]
Many objects that we normally deal with in quantum physics are only visible with special microscopes—individual molecules or atoms, for example. However, the quantum objects that Elena Redchenko works with at the Institute for Atomic […]
Quantum 9, 1636 (2025). https://doi.org/10.22331/q-2025-02-18-1636 Pebble games are popular models for analyzing time-space trade-offs. In particular, reversible pebble game strategies are frequently applied in quantum algorithms like Grover’s search to efficiently simulate classical computation on […]
Quantum 9, 1635 (2025). https://doi.org/10.22331/q-2025-02-18-1635 We present a cooling algorithm for ground state preparation of fermionic Hamiltonians. Our algorithm makes use of the Hamiltonian simulation of the considered system coupled to an ancillary fridge, which […]
Quantum 9, 1634 (2025). https://doi.org/10.22331/q-2025-02-18-1634 Quasiprobabilistic cutting techniques allow us to partition large quantum circuits into smaller subcircuits by replacing non-local gates with probabilistic mixtures of local gates. The cost of this method is a […]
“Obviously” is a dangerous word, even in scenarios that seem simple. Suppose, for instance, you need to do an important computation. You get to choose between two computers that are almost identical, except that one […]
Insider Brief: Researchers from CQT and UNSW experimentally demonstrated that nuclear spin precession is fundamentally quantum, overturning the long-held assumption that it behaves classically. By measuring a single antimony nucleus in a precisely prepared quantum […]
Insider Brief: Telefónica España partnered with the Government of Biscay to support its quantum technology strategy, strengthening public-private collaboration in advancing quantum research and industrial applications. The partnership will establish a quantum computing infrastructure, including […]
What makes something quantum? This question has kept a small but dedicated fraction of the world’s population—most of them quantum physicists—up at night for decades. Click to rate this post! [Total: 0 Average: 0]You have […]
