# Quantum computer toggle switch

## Appears In

                        - NIST ‘Toggle Switch’ Can Help Quantum Computers Cut Through the Noise
                        - NIST Collaborates With Raytheon BBN & Universities to Create Quantum Computer Toggle Switch
                        - National Institute of Standards and Technology

This photo shows the central working region of the device. In the lower section, the three large rectangles (light blue) represent the two quantum bits, or qubits, at right and left and the resonator in the center. In the upper, magnified section, driving microwaves through the antenna (large dark-blue rectangle at bottom) induces a magnetic field in the SQUID loop (smaller white square at center, whose sides are about 20 micrometers long). The magnetic field activates the toggle switch. The microwaves’ frequency and magnitude determine the switch’s position and strength of connection among the qubits and resonator.
