Layered Architecture for Quantum Computing
Physical Review X, 2012 We develop a layered quantum-computer architecture, which is a systematic framework for tackling the individual challenges of developing a quantum computer while constructing a cohesive device design.

Generation of thermofield double states and critical ground states with a quantum computer. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Our experiment prepares two types of nontrivial quantum states on a trapped ion quantum computer: the thermofield double state of the transverse-field Ising model at arbitrary temperature and the quantum critical state of the zero ...

Topological order from measurements and feed-forward on a trapped ion quantum computer [PDF]
Communications Physics, 2023 Quantum systems evolve in time in one of two ways: through the Schrödinger equation or wavefunction collapse. So far, deterministic control of quantum many-body systems in the lab has focused on the former, due to the probabilistic nature of measurements.

Exact and efficient Lanczos method on a quantum computer [PDF]
Quantum, 2022 We present an algorithm that uses block encoding on a quantum computer to exactly construct a Krylov space, which can be used as the basis for the Lanczos method to estimate extremal eigenvalues of Hamiltonians.

Realization of quantum signal processing on a noisy quantum computer [PDF]
npj Quantum Information, 2023 Quantum signal processing (QSP) is a powerful toolbox for the design of quantum algorithms and can lead to asymptotically optimal computational costs. Its realization on noisy quantum computers without fault tolerance, however, is challenging because it ...

Quantum support vector machines for classification and regression on a trapped-ion quantum computer [PDF]
Quantum Machine Intelligence, 2023 Quantum machine learning is a rapidly growing field at the intersection of quantum computing and machine learning. In this work, we examine our quantum machine learning models, which are based on quantum support vector classification (QSVC) and quantum ...
