Fermionic Chern-Simons Theory of SU(4) Fractional Quantum Hall Effect
, 2011 We develop a Fermionic Chern-Simons (CS) theory for the fractional quantum Hall effect in monolayer graphene with SU(4) symmetry, arising from the spin and the valley degrees of freedom, which involves four distinct CS gauge fields.

Spin quantum number as quantum resource for quantum sensing
Identifying quantum resources for quantum sensing is of paramount importance. Up to date, two quantum resources has been widely recognized: the number $N$ of entangled quantum probes and the coherent evolution time $T$. Here we identify the spin quantum number $S$ of high-spin systems as another quantum resource, which can improve the sensing precision

COMPLEX RATIONAL NUMBERS IN QUANTUM MECHANICS [PDF]
International Journal of Modern Physics B, 2006 A binary representation of complex rational numbers and their arithmetic is described that is not based on qubits. It takes account of the fact that 0s in a qubit string do not contribute to the value of a number. They serve only as place holders. The representation is based on the distribution of four types of systems, corresponding to +1, -1, +i, -i,

Quantum scissor from exact generalized photon number statistics
Scientific ReportsWe report the close form expressions of the photon number statistics for a generalized coherent state and a generalized photon-added coherent state, which are shown to be crucial for proposing a variety of quantum scissor operations.

Quantum Random Number Generation Using a Quanta Image Sensor
Sensors, 2016 A new quantum random number generation method is proposed. The method is based on the randomness of the photon emission process and the single photon counting capability of the Quanta Image Sensor (QIS).

Complexity and capacity bounds for quantum channels
, 2017 We generalise some well-known graph parameters to operator systems by considering their underlying quantum channels. In particular, we introduce the quantum complexity as the dimension of the smallest co-domain Hilbert space a quantum channel requires to

Quantum walk on distinguishable non-interacting many-particles and indistinguishable two-particle
, 2012 We present an investigation of many-particle quantum walks in systems of non-interacting distinguishable particles. Along with a redistribution of the many-particle density profile we show that the collective evolution of the many-particle system ...

An optical chip for self-testing quantum random number generation
APL Photonics, 2020 We present an implementation of a semi-device-independent protocol of the generation of quantum random numbers in a fully integrated silicon chip. The system is based on a prepare-and-measure scheme, where we integrate a partially trusted source of ...
