Motivated by their necessity for most fault-tolerant quantum computation schemes, we formulate a resource theory for magic states. We first show that robustness of magic is a well-behaved magic monotone that operationally quantifies the classical simulation overhead for a Gottesman-Knill type scheme using ancillary magic states. Our framework subsequently finds immediate application in the task of synthesizing non-Clifford gates using magic states.

An essential prerequisite for quantum information processing is precise coherent control of the dynamics of quantum systems or quantum bits (qubits). Most of the control sequences implemented in quantum experiments are developed and designed based on the assumption of having ideal (closed) quantum coherent systems.

Colloquium featuring Heejeong Jeong - Hong Kong University of Science and Technology

Optical precursors are transient electromagnetic wave packets propagating precisely at the speed of light in vacuum through a dispersive and absorptive dielectric. Even though its existence was conjectured by Sommerfeld and Brillouin 100 years ago, the detection seemed to be impossible due to its exceedingly small amplitude and femtosecond time scale in ordinary linear dispersive media.
