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 …

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

We introduce a novel measure for the quantum property of “nonstabilizerness”—commonly
known as “magic”—by considering the Rényi entropy of the probability distribution …

Recent work has explored using the stabilizer formalism to classically simulate quantum
circuits containing a few non-Clifford gates. The computational cost of such methods is …

It is vital to minimize the impact of errors for near-future quantum devices that will lack the
resources for full fault tolerance. Two quantum error mitigation (QEM) techniques have been …

Nonstabilizerness, also known as “magic,” stands as a crucial resource for achieving a
potential advantage in quantum computing. Its connection to many-body physical …

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 …

The scarcity of qubits is a major obstacle to the practical usage of quantum computers in the
near future. To circumvent this problem, various circuit knitting techniques have been …

We improve the number of T gates needed to perform an n-bit adder from $8 n+ O (1) $ to $4
n+ O (1) $. We do so via a" temporary logical-AND" construction which uses four T gates to …

We develop a resource theory for continuous-variable systems grounded on operations
routinely available within current quantum technologies. In particular, the set of free …
