Objective No. 5: Measurement
Measurement of magnetic qubits can be affected by their coupling to individual microSQUIDs. One operation mode of a SQUID device is a very sensitive magnetometer which is equivalent to the projection of the qubit spin onto the Szbasis.
Current state-of-the-art with microSQUID technology permits the measurement of spin down to the scale of S = 10000.
Our intention is to develop new microSQUIDs and new nanodevices to enable thedetection of individual magnetic cluster/particle qubits with S values of a few hundreds or less.
The measurement operation should be accompanied by the control in the deposition of the magnetic qubit within the SQUID loop.
This point is crucial because the design and construction of a pilot quantum computer with only a few magnetic qubits will depend strongly on the sensitivity of the microSQUID.
