Theory indicates that a quantum computer manipulating quantum information by means of geometric phases in Hilbert space (h\phantom\rule00exo\phantom\rule00exl\phantom\rule00exo\phantom\rule00exn\phantom\rule00exo\phantom\rule00exm\phantom\rule00exi\phantom\rule00exc q\phantom\rule00exu\phantom\rule00exa\phantom\rule00exn\phantom\rule00ext\phantom\rule00exu\phantom\rule00exm c\phantom\rule00exo\phantom\rule00exm\phantom\rule00exp\phantom\rule00exu\phantom\rule00ext\phantom\rule00exi\phantom\rule00exn\phantom\rule00exg) could be resilient to certain forms of noise. Two-qubit nonadiabatic holonomies are important for computing architectures based on fixed-frequency superconducting qubits, as they provide the means to directly realize an exchange-type operation. Here researchers implement a nonadiabatic holonomic operation between two such qubits connected by a microwave resonator, to create entangled states. As proof of principle, this operation is used to calculate the ground state of molecular hydrogen.
