Quantum 10, 2004 (2026). https://doi.org/10.22331/q-2026-02-11-2004 The QMA-completeness of the local Hamiltonian problem is a landmark result of the field of Hamiltonian complexity that studies the computational complexity of problems in quantum many-body physics. Since its […]
Quantum 10, 2003 (2026). https://doi.org/10.22331/q-2026-02-10-2003 Quantum error mitigation techniques mimic noiseless quantum circuits by running several related noisy circuits and combining their outputs in particular ways. How well such techniques work is thought to depend […]
Quantum 10, 2002 (2026). https://doi.org/10.22331/q-2026-02-10-2002 Certified randomness has a long history in quantum information, with many potential applications. Recently Aaronson and Hung proposed a novel public certified randomness protocol based on existing random circuit sampling […]
Quantum 10, 2001 (2026). https://doi.org/10.22331/q-2026-02-09-2001 Graph states are a powerful class of entangled states with numerous applications in quantum communication and quantum computation. Local Clifford (LC) operations that map one graph state to another can […]
Quantum 10, 2000 (2026). https://doi.org/10.22331/q-2026-02-09-2000 While 2-level systems, aka qubits, are a natural choice to perform a logical quantum computation, the situation is less clear at the physical level. Encoding information in higher-dimensional physical systems […]
Quantum 10, 1999 (2026). https://doi.org/10.22331/q-2026-02-09-1999 The Sachdev–Ye–Kitaev (SYK) model is a prominent model of strongly interacting fermions that serves as a toy model of quantum gravity and black hole physics. In this work, we study […]
Quantum 10, 1998 (2026). https://doi.org/10.22331/q-2026-02-09-1998 We present a quantum variational algorithm based on a novel circuit that generates all permutations that can be spanned by one- and two-qubits permutation gates. The construction of the circuits […]
Quantum 10, 1997 (2026). https://doi.org/10.22331/q-2026-02-06-1997 We describe an efficient, fully fault-tolerant implementation of Measurement-Based Quantum Computation (MBQC) in the 3D cluster state. The two key novelties are (i) the introduction of a lattice defect in […]
Quantum 10, 1996 (2026). https://doi.org/10.22331/q-2026-02-06-1996 This work shows that minimizing the depth of a quantum circuit composed of commuting operations reduces to a vertex coloring problem on an appropriately constructed graph, where gates correspond to […]
Quantum 10, 1995 (2026). https://doi.org/10.22331/q-2026-02-03-1995 Characterizing entanglement of systems composed of multiple particles is a very complex problem that is attracting increasing attention across different disciplines related to quantum physics. The task becomes even more […]
