Scatter three points in a plane, then measure the distances between every pair of them. In all likelihood, you’ll find three different distances. But if you arrange the points in an equilateral triangle, then every […]
Seeking a method for reducing error in noisy quantum systems, Kajsa Williams and Louis-S. Bouchard, researchers at the Center for Quantum Science and Engineering at the University of California, Los Angeles, implemented and evaluated single-qubit […]
In an insightful discussion on “New Horizons in Quantum Computing” during The Enterprise Sessions, Professor Anthony Laing, a pioneering figure in the quantum computing (QC) arena and CEO of Duality Quantum Photonics, shared his journey […]
Quantum many-body systems are things such as atomic nuclei that consist of many tiny particles moving in complex ways. This makes it extremely difficult to predict how the systems behave as the particles interact. To […]
Physicists at Julius-Maximilians-Universität Würzburg (JMU) have made a discovery that could boost the understanding of the role of entanglement in high-temperature copper oxide superconductors. The low-energy quasiparticles of these enigmatic quantum materials, so-called Zhang-Rice singlets, […]
Quantum 8, 1316 (2024). https://doi.org/10.22331/q-2024-04-09-1316 This work proposes double-bracket iterations as a framework for obtaining diagonalizing quantum circuits. Their implementation on a quantum computer consists of interlacing evolutions generated by the input Hamiltonian with diagonal […]
Quantum 8, 1315 (2024). https://doi.org/10.22331/q-2024-04-09-1315 We analyze utility of communication channels in absence of any short of quantum or classical correlation shared between the sender and the receiver. To this aim, we propose a class […]
Quantum 8, 1314 (2024). https://doi.org/10.22331/q-2024-04-09-1314 The quantum rate-distortion function plays a fundamental role in quantum information theory, however there is currently no practical algorithm which can efficiently compute this function to high accuracy for moderate […]
Quantum 8, 1313 (2024). https://doi.org/10.22331/q-2024-04-09-1313 Variational quantum algorithms (VQAs) represent a promising approach to utilizing current quantum computing infrastructures. VQAs are based on a parameterized quantum circuit optimized in a closed loop via a classical […]
Quantum 8, 1312 (2024). https://doi.org/10.22331/q-2024-04-09-1312 Several classes of quantum circuits have been shown to provide a quantum computational advantage under certain assumptions. The study of ever more restricted classes of quantum circuits capable of quantum […]
