A universal fault-tolerant quantum computer that can efficiently solve problems such as
integer factorization and unstructured database search requires millions of qubits with low …

Quantum materials exhibit a wide array of exotic phenomena and practically useful
properties. A better understanding of these materials can provide deeper insights into …

We report an accurate and efficient classical simulation of a kicked Ising quantum system on
the heavy hexagon lattice. A simulation of this system was recently performed on a 127-qubit …

For the first time in history, we are seeing a branching point in computing paradigms with the
emergence of quantum processing units (QPUs). Extracting the full potential of computation …

Quantum error mitigation has been proposed as a means to combat unwanted and
unavoidable errors in near-term quantum computing without the heavy resource overheads …

We propose a new method to extend the size of a quantum computation beyond the number
of physical qubits available on a single device. This is accomplished by randomly inserting …

The use of kernel functions is a common technique to extract important features from
datasets. A quantum computer can be used to estimate kernel entries as transition …

In this paper, we eliminate the classical outer learning loop of the quantum approximate
optimization algorithm (QAOA) and present a strategy to find good parameters for QAOA …

As Moore's law reaches its limits, quantum computers are emerging that hold promise to
dramatically outperform classical computers. It is now possible to build quantum processors …

A central question of quantum computing is determining the source of the advantage of
quantum computation over classical computation. Even though simulating quantum …
