The variational quantum eigensolver (or VQE), first developed by Peruzzo et al.(2014), has
received significant attention from the research community in recent years. It uses the …

Qudit is a multi-level computational unit alternative to the conventional 2-level qubit.
Compared to qubit, qudit provides a larger state space to store and process information, and …

We introduce a novel approach to evaluate the nonstabilizerness of an N-qubits matrix
product state (MPS) with bond dimension χ. In particular, we consider the recently …

A central result in the foundations of quantum mechanics is the Kochen-Specker theorem. In
short, it states that quantum mechanics is in conflict with classical models in which the result …

Catalysts open up new reaction pathways that can speed up chemical reactions while not
consuming the catalyst. A similar phenomenon has been discovered in quantum information …

Nonstabilizerness, also known as magic, quantifies the number of non-Clifford operations
needed to prepare a quantum state. As typical measures either involve minimization …

Nonstabilizerness or magic resource characterizes the amount of non-Clifford operations
needed to prepare quantum states. It is a crucial resource for quantum computing and a …

Motivated by their necessity for most fault-tolerant quantum computation schemes, we
formulate a resource theory for magic states. First, we show that robustness of magic is a …

We propose examples of a hybrid quantum-classical simulation where a classical computer
assisted by a small quantum processor can efficiently simulate a larger quantum system …

Quantum resource theories (QRTs) offer a highly versatile and powerful framework for
studying different phenomena in quantum physics. From quantum entanglement to quantum …
