Microwaves for quantum
Currently there are many breakthrough developments worldwide in quantum computing. Some types of quantum bits (qubits) have an interaction with microwave fields, by which they are controlled and read out after the computation has finalized. There is a coupling between the quantum domain and the microwave domain, so microwaves are used to interface. Traditionally each qubit was controlled individually by expensive microwave equipment, but with increasing number of qubits this doesn’t extend very well. Linear scaling of equipment with the number of qubits will enter a dead-end street.
We present our patented invention, which aims at solving this issue. This microwave vector switch matrix is our second prototype which has been used to prove the concept in many quantum experiments, which resulted in a scientific paper on the architecture. The talk will be about the control scale up and third-generation microwave hardware we are currently developing.
