For quantum computers to successfully solve real-world problems, it is necessary to tackle
the challenge of noise: the errors that occur in elementary physical components due to …

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Many-body open quantum systems balance internal dynamics against decoherence and
measurements induced by interactions with an environment,. Quantum circuits composed of …

Current gate-based quantum computers have the potential to provide a computational
advantage if algorithms use quantum hardware efficiently. To make combinatorial …

We characterize the variational power of quantum circuit tensor networks in the
representation of physical many-body ground states. Such tensor networks are formed by …

The ground state of the spin-1 Affleck, Kennedy, Lieb, and Tasaki (AKLT) model is a
paradigmatic example of both a matrix product state and a symmetry-protected topological …

Trapped ions offer long coherence times and high fidelity, programmable quantum
operations, making them a promising platform for quantum simulation of condensed matter …

Quantum many-body control is a central milestone en route to harnessing quantum
technologies. However, the exponential growth of the Hilbert space dimension with the …

We introduce a class of quantum circuits that are unitary along three distinct “arrows of time.”
These dynamics share some of the analytical tractability of “dual-unitary” circuits, while …

We develop holographic quantum simulation techniques to prepare correlated electronic
ground states in quantum matrix-product-state (QMPS) form, using far fewer qubits than the …
