Abstract
According to one aspect of the disclosure, a system for performing quantum computations includes: a first environment for being maintained at an ambient temperature, having a classical computing processor; and a second environment for being maintained at a cryogenic temperature, having a plurality of qubits and a multiplexing circuit coupled to the plurality of qubits, each of the plurality of qubits having a gap transition frequency; wherein the classical computing processor is configured to change the states of each of the plurality of qubits by controlling the multiplexing circuit to couple particular ones of the plurality of qubits to a pulsed baseband waveform.

A system for performing quantum computations, the system comprising:
- a first environment for being maintained at an ambient temperature, having a classical computing processor;
- and
- a second environment for being maintained at a cryogenic temperature, having a plurality of qubits and a multiplexing circuit coupled to the plurality of qubits, each of the plurality of qubits having a respective gap transition frequency,
- wherein the classical computing processor is configured to change a state of particular ones of the of the plurality of qubits by controlling the multiplexing circuit to couple the particular ones of the plurality of qubits to a pulsed baseband waveform,
- wherein the pulsed baseband waveform comprises a non-adiabatic waveform that is not resonant with respect to the respective gap transition frequencies of the particular ones of the plurality of qubits.
A quantum computing system comprising:
- a classical computing processor;
- a quantum processing unit (QPU) having a plurality of qubits with respective gap transition frequencies;
- and
- a multiplexer configured to couple particular ones of the plurality of qubits to a pulsed baseband waveform responsive to commands received from the classical computing processor,
