Quantum 8, 1317 (2024). https://doi.org/10.22331/q-2024-04-30-1317 Accelerated light has been demonstrated with laser light and diffraction. Within the diffracting field it is possible to identify a portion that carries most of the beam energy, which propagates […]
In 2024 Quantum will celebrate 7 years since the first publications! From that first batch of papers, the journal grew to over 1300 published articles. This growth was made possible by our incredible team of […]
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 […]
Quantum 8, 1311 (2024). https://doi.org/10.22331/q-2024-04-08-1311 We explore the possibility of adding complex absorbing potential at the boundaries when solving the one-dimensional real-time Schrödinger evolution on a grid using a quantum computer with a fully quantum […]
Quantum 8, 1310 (2024). https://doi.org/10.22331/q-2024-04-08-1310 In this paper, I cut the cost of Y basis measurement and initialization in the surface code by nearly an order of magnitude. Fusing twist defects diagonally across the surface […]
Quantum 8, 1309 (2024). https://doi.org/10.22331/q-2024-04-08-1309 Quantum span program algorithms for function evaluation sometimes have reduced query complexity when promised that the input has a certain structure. We design a modified span program algorithm to show […]
