Quantum 8, 1401 (2024). https://doi.org/10.22331/q-2024-07-10-1401 We show how to efficiently simulate pure quantum states in one dimensional systems that have both finite energy density and vanishingly small energy fluctuations. We do so by studying the […]
Quantum 8, 1400 (2024). https://doi.org/10.22331/q-2024-07-10-1400 Majorana zero modes (MZMs) are promising candidates for topologically-protected quantum computing hardware, however their large-scale use will likely require quantum error correction. Majorana surface codes (MSCs) have been proposed to […]
Quantum 8, 1399 (2024). https://doi.org/10.22331/q-2024-07-04-1399 Trapdoor claw-free functions (TCFs) are immensely valuable in cryptographic interactions between a classical client and a quantum server. Typically, a protocol has the quantum server prepare a superposition of two-bit […]
Quantum 8, 1398 (2024). https://doi.org/10.22331/q-2024-07-04-1398 We introduce a new class of random Gottesman-Kitaev-Preskill (GKP) codes derived from the cryptanalysis of the so-called NTRU cryptosystem. The derived codes are $good$ in that they exhibit constant rate […]
Quantum 8, 1397 (2024). https://doi.org/10.22331/q-2024-07-04-1397 Measurement-Based Quantum Computation (MBQC) is a model of quantum computation, which uses local measurements instead of unitary gates. Here we explain that the MBQC procedure has a fundamental basis in […]
Quantum 8, 1396 (2024). https://doi.org/10.22331/q-2024-07-03-1396 The most efficient automated way to construct a large class of quantum photonic experiments is via abstract representation of graphs with certain properties. While new directions were explored using Artificial […]
Quantum 8, 1395 (2024). https://doi.org/10.22331/q-2024-07-03-1395 Variational Quantum Algorithms (VQAs) and Quantum Machine Learning (QML) models train a parametrized quantum circuit to solve a given learning task. The success of these algorithms greatly hinges on appropriately […]
Quantum 8, 1394 (2024). https://doi.org/10.22331/q-2024-07-02-1394 We simulate the logical Hadamard gate in the surface code under a circuit-level noise model, compiling it to a physical circuit on square-grid connectivity hardware. Our paper is the first […]
Quantum 8, 1393 (2024). https://doi.org/10.22331/q-2024-07-02-1393 We derive an analytical expression of a Wigner function that approximately describes the time evolution of the one-dimensional motion of a particle in a nonharmonic potential. Our method involves two […]
Quantum 8, 1392 (2024). https://doi.org/10.22331/q-2024-07-02-1392 Semiconductor platforms are emerging as a promising architecture for storing and processing quantum information, e.g., in quantum dot spin qubits. However, charge noise coming from interactions between the electrons is […]
