A note on Majorana representation of quantum states
Chi-Kwong Li, Mikio Nakahara
By the Majorana representation, for any there is a one-one correspondence between a quantum state of dimension and qubits represented as points in the Bloch…
Unified Derivation of Uncertainty Relations and Their Saturation Conditions
Chi-Kwong Li, Mikio Nakahara
We analyze uncertainty relations due to Kennard, Robertson, Schrödinger, Maccone and Pati in a unified way from matrix theory point of view. Short proofs are given to these uncerta…
Counterdiabatic Formalism of Shortcuts to Adiabaticity
Mikio Nakahara
Pedagogical introduction to counterdiabatic formalism of shortcuts to adiabaticity is given so that the readers are accessible to some of more specialized articles in the rest of t…
Controllable non-Markovianity in phase relaxation
Shingo Kukita, Yasushi Kondo, Mikio Nakahara
Recently remarkable progress in quantum technology has been witnessed. In view of this it is important to investigate an open quantum system as a model of such quantum devices. Qua…
On the explicit constructions of certain unitary -designs
Eiichi Bannai, Mikio Nakahara, Da Zhao +1
Unitary -designs are `good' finite subsets of the unitary group that approximate the whole unitary group well. Unitary -designs have been applied in randomized…
Acoustic black holes in curved spacetime and emergence of analogue Minkowski metric
Xian-Hui Ge, Mikio Nakahara, Sang-Jin Sin +2
Gravity is not only able to be mimicked in flat spacetimes, but also in curved spacetimes. We study analogue gravity models in curved spacetime by considering the relativistic Gros…
