Quasiparticle Poisoning of Superconducting Qubits from Resonant Absorption of Pair-Breaking Photons
Quasiparticle Poisoning of Superconducting Qubits from Resonant Absorption of Pair-Breaking Photons
The ideal superconductor provides a pristine environment for the delicate states of a quantum computer: because there is an energy gap to excitations, there are no spurious modes with which the qubits can interact, causing irreversible decay of the quantum state. As a practical matter, however, there exists a high …
