Quantum 8, 1279 (2024). https://doi.org/10.22331/q-2024-03-13-1279 Multi-qubit entangling interactions arise naturally in several quantum computing platforms and promise advantages over traditional two-qubit gates. In particular, a fixed multi-qubit Ising-type interaction together with single-qubit X-gates can be […]
In cybersecurity, “quantum security” is pivotal due to quantum computing’s potential to undermine encryption. This emerging field aims to develop quantum-resistant algorithms to protect digital communications against quantum threats. With quantum computers poised to break […]
Exposing the emptiness of the h-word: how claims of hyperbole ring hollow; and how nobody, not even today’s experts, can possibly know the limits of Quantum. By Shai Phillips President, PSIRCH In a monthly segment […]
Quantum 8, 1278 (2024). https://doi.org/10.22331/q-2024-03-13-1278 Subspace diagonalisation methods have appeared recently as promising means to access the ground state and some excited states of molecular Hamiltonians by classically diagonalising small matrices, whose elements can be […]
Quantum 8, 1277 (2024). https://doi.org/10.22331/q-2024-03-13-1277 Studies have shown that the Hilbert spaces of non-Hermitian systems require nontrivial metrics. Here, we demonstrate how evolution dimensions, in addition to time, can emerge naturally from a geometric formalism. […]
Quantum 8, 1276 (2024). https://doi.org/10.22331/q-2024-03-13-1276 We propose a systematic and efficient quantum circuit composed solely of Clifford gates for simulating the ground state of the surface code model. This approach yields the ground state of […]
