Demonstrating an unconditional separation between quantum and classical information resources
William Kretschmer, Sabee Grewal, Matthew DeCross +8
A longstanding goal in quantum information science is to demonstrate quantum computations that cannot be feasibly reproduced on a classical computer. Such demonstrations mark major…

Breaking even with magic: demonstration of a high-fidelity logical non-Clifford gate
Shival Dasu, Simon Burton, Karl Mayer +7
Encoding quantum information to protect it from errors is essential for performing large-scale quantum computations. Performing a universal set of quantum gates on encoded states d…

Order-of-magnitude extension of qubit lifetimes with a decoherence-free subspace quantum error correction code
Shival Dasu, Ben Criger, Cameron Foltz +9
Constructing an efficient and robust quantum memory is central to the challenge of engineering feasible quantum computer architectures. Quantum error correction codes can solve thi…
