Qudit low-density parity-check codes
Daniel J. Spencer, Andrew Tanggara, Tobias Haug +2
Qudits offer significant advantages over qubit-based architectures, including more efficient gate compilation, reduced resource requirements, improved error-correction primitives,…
Schrodinger's Field Equation
Jacek Mroczkowski
The intrinsic and dynamic kinetic energies, and the potential energies of electron states in the hydrogen atom, were determined using the operator formalism in the Schrodinger nonr…
Quantifying Irreversibility via Bayesian Subjectivity for Classical & Quantum Linear Maps
Lizhuo Liu, Clive Cenxin Aw
In both classical and quantum physics, irreversible processes are described by maps that contract the space of states. The change in volume has often been taken as a natural quanti…
Certifying the quantumness of a nuclear spin qudit through its uniform precession
Arjen Vaartjes, Martin Nurizzo, Lin Htoo Zaw +16
Spin precession is a textbook example of dynamics of a quantum system that exactly mimics its classical counterpart. Here we challenge this view by certifying the quantumness of ex…
Restricted Randomized Benchmarking with Universal Gates of Fixed Sequence Length
Mohsen Mehrani, Kasra Masoudi, Rawad Mezher +2
The standard randomized benchmarking protocol requires access to often complex operations that are not always directly accessible. Compiler optimization does not always ensure equa…
Hilbert-Space Ergodicity in Driven Quantum Systems: Obstructions and Designs
Saúl Pilatowsky-Cameo, Iman Marvian, Soonwon Choi +1
Despite its long history, a canonical formulation of quantum ergodicity that applies to general classes of quantum dynamics, including driven systems, has not been fully establishe…
