Quantum 10, 2035 (2026). https://doi.org/10.22331/q-2026-03-20-2035 We present an efficient spin-photon interface for free-space vertical emission coupling. Using a dipole model, we show that our design achieves a far-field collection efficiency of 96% at the numerical […]
Quantum 10, 2034 (2026). https://doi.org/10.22331/q-2026-03-20-2034 In this work, a novel quantum neural network is introduced as a means to approximate any unitary evolution through the Standard Recursive Block Basis (SRBB) and is subsequently redesigned with […]
Quantum 10, 2033 (2026). https://doi.org/10.22331/q-2026-03-20-2033 We design Snowflake, a quantum error correction decoder that, for the surface code under circuit-level noise, is roughly 25% more accurate than the Union-Find decoder, with a better mean runtime […]
Quantum 10, 2032 (2026). https://doi.org/10.22331/q-2026-03-18-2032 We propose applying the adiabatic algorithm to prepare high-energy eigenstates of integrable models on a quantum computer. We first review the standard adiabatic algorithm to prepare ground states in each […]
Quantum 10, 2031 (2026). https://doi.org/10.22331/q-2026-03-16-2031 We are interested in the simulation of open quantum systems governed by the Lindblad master equation in an infinite-dimensional Hilbert space. To simulate the solution of this equation, the standard […]
Quantum 10, 2030 (2026). https://doi.org/10.22331/q-2026-03-16-2030 Photon loss rates set an effective upper limit on the size of computations that can be run on current linear optical quantum devices. We present a family of techniques designed […]
Quantum 10, 2029 (2026). https://doi.org/10.22331/q-2026-03-16-2029 Finding the ground state of strongly-interacting fermionic systems is often the prerequisite for fully understanding both quantum chemistry and condensed matter systems. The Sachdev–Ye–Kitaev (SYK) model is a representative example […]
Quantum 10, 2028 (2026). https://doi.org/10.22331/q-2026-03-16-2028 We introduce and investigate a data access model $textit{(approximate sample and query)}$ that is satisfiable by the preparation and measurement of block encoded states, as well as in contexts such […]
Quantum 10, 2027 (2026). https://doi.org/10.22331/q-2026-03-13-2027 We define a quantum learning task called $textit{agnostic tomography}$, where given copies of an arbitrary state $rho$ and a class of quantum states $mathcal{C}$, the goal is to output a […]
