Physically motivated decompositions of single-qutrit gates

Aryan Iliat, Mark Byrd, Sahel Ashhab +1

Although only two quantum states of a physical system are often used to encode quantum information in the form of qubits, many levels can in principle be used to obtain qudits and…

Going beyond quantum Markovianity and back to reality: An exact master equation study

Zhao-Ming Wang, S. L. Wu, Mark S. Byrd +1

The precise characterization of dynamics in open quantum systems often presents significant challenges, leading to the introduction of various approximations to simplify a model. O…

Fault Tolerant Quantum Error Mitigation

Alvin Gonzales, Anjala M Babu, Ji Liu +2

Typically, fault-tolerant operations and code concatenation are reserved for quantum error correction due to their resource overhead. Here, we show that fault tolerant operations h…

Hybrid noise protection of logical qubits for universal quantum computation

Zhao-Ming Wang, Feng-Hua Ren, Mark S. Byrd +1

Quantum computers now show the promise of surpassing any possible classical machine. However, errors limit this ability and current machines do not have the ability to implement er…

Some Entanglement Survives Most Measurements

Alvin Gonzales, Daniel Dilley, Mark Byrd

To prepare quantum states and extract information, it is often assumed that one can perform a perfectly projective measurement. Such measurements can achieve an uncorrelated system…

Modularized and Scalable Compilation for Double Quantum Dot Quatum Computing

Run-Hong He, Xu-Sheng Xu, Mark S. Byrd +1

Any quantum program on a realistic quantum device must be compiled into an executable form while taking into account the underlying hardware constraints. Stringent restrictions on…
