Abstract
Example embodiments relate to delivery of qubit drive signals to a cryogenic environment of a quantum computer. Qubit drive signal(s) may be conveyed to the cryogenic environment as optical signal(s). The optical signal(s) may be transduced to radio frequency signal(s) at the cryogenic environment for driving qubit(s). Apparatuses and methods are disclosed.
Claims18
An apparatus, comprising:
- at least one electro-optic modulator configured to modulate at least one optical signal with at least one input radio frequency signal at a non-cryogenic environment of a quantum computer;
- at least one optical fiber configured to convey the at least one optical signal to a cryogenic environment of the quantum computer;
- at least one optomechanical transducer configured to transduce the at least one optical signal to at least one radio frequency signal at the cryogenic environment of the quantum computer;
- and
- driving circuitry configured to drive at least one qubit of the quantum computer based on the at least one radio frequency signal.
