# Theory and Experiment

The Centre for Quantum technology is a Research Group at the University of KwaZulu-Natal in Durban, South Africa. The Centre is on the Westville Campus

## Location:

The Joint Quantum Institute (JQI) brings together leading quantum scientists from the Department of Physics of the University of Maryland (UMD), the National Institute of Standards and Technology (NIST) and the Laboratory for Physical Sciences (LPS). Each institution brings to JQI major experimental and theoretical research programs that are dedicated to the goals of controlling and exploiting quantum systems.

JQI's objectives are to:

- serve as a world-class research institute, conducting fundamental investigations of coherent quantum phenomena and thereby laying the foundation for engineering and controlling complex quantum systems capable of using the coherence and entanglement of quantum mechanics;

- maintain and enhance the nation's leading role in high technology through a powerful collaboration among NIST, UMD and LPS; and

- provide a unique, interdisciplinary center for the interchange of ideas among atomic physics, condensed matter and quantum information scientists.

My group explanation is written in the following. The tentative website is http://qm.ims.ac.jp/

Honestly speaking, I am looking for the ultimate goal on my research career. The Nature knows many interesting problems but unfortunately we have not yet analyzed for any physical systems. Therefore, I have to make "new" and "interesting" problems inside the Nature. Now, I am continuing the following projects;

1. Quantum Measurement in Quantum Field Theory

How should we understand the Young's double experiment for the single particle from the viewpoint of quantum field theory?

The scattering matrix is only measurable?

2. Weak value initiated by Yakir Aharonov is useful? (continuing from Ph.D. thesis work)

Relationship to the weak measurement

Relationship to the measurement outcome

Reconstruction of standard quantum mechanics

What are the applications?

3. How should we understand the non-equilibrium and open dissipative systems?

3-1. Axiomatic approach: reconstruction of thermodynamics and statistical mechanics

Key idea came from Leon Brilloiun: to connect any physical systems to informational/operational contexts

3-2. Axiomatic approach: reconsideration of axiom of thermodynamics from mathematical physics (stochastic approach)

What condition is the equilibrium state?

Time and space scales should be included in?

3-3. Pragmatic approach: to collaborate any systems with the experimental guys

Exciton-polariton condensation on the two dimensional semiconductor system with the micro cavity

Fast phenomena in quantum dots

4. Quantum dynamics toy model: Quantum walks (continuing from Ph.D. thesis work)

What are the applications?

How to implement it?

5. Other interesting projects!! Welcome to me.

The common concept is to understand the time or dynamical features in the Nature. When you are interested in my group in IMS or other groups in IMS. Please contact me, yshikano_at_ims.ac.jp.
