Weak and continuous measurements in superconducting circuits
Speaker(s): Justin Dressel
Abstract: Superconducting circuit technology has rapidly developed over the past several years to become a leading contender for realizing a scalable quantum computer. Modern circuit designs are based on the transmon qubit, which coherently superposes macroscopic charge oscillations. Measurements of a transmo... read more

PIRSA:16060099  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Delayed choice qubit Lorentz rotations
Speaker(s): Justin Dressel
Abstract: For a spin 1/2 (a qubit), Hamiltonian evolution is equivalent to an elliptic rotation of the (Bloch) spin vector in 3D space. In contrast, measurement alters the state norm, so may not be described as such a rotation. Nevertheless, extending the 3D spin vector to a 4D "spacetime" representation allo... read more
