Nonadiabatic quantum control of quantum dot arrays with fixed exchange using Cartan decomposition
David W. Kanaar, Utkan Güngördü, J. P. Kestner
In semiconductor spin qubits which typically interact through short-range exchange coupling, shuttling of spin is a practical way to generate quantum operations between distant qub…
Parafermion stabilizer codes
Utkan Güngördü, Rabindra Nepal, Alexey A. Kovalev
We define and study parafermion stabilizer codes which can be viewed as generalizations of Kitaev's one dimensional model of unpaired Majorana fermions. Parafermion stabilizer code…
Nonadiabatic holonomic one-qubit gates
Takumi Nitanda, Utkan Güngördü, Mikio Nakahara
Adiabatic quantum gate implementation generally takes longer time, which is disadvantageous in view of decoherence. In this report we implement several essential one-qubit quantum…
Dynamical invariants for quantum control of four-level systems
Utkan Güngördü, Yidun Wan, Mohammad Ali Fasihi +1
We present a Lie-algebraic classification and detailed construction of the dynamical invariants, also known as Lewis-Riesenfeld invariants, of the four-level systems including two-…
Minimal and Robust Composite Two-Qubit Gates with Ising-Type Interaction
Tsubasa Ichikawa, Utkan Güngördü, Masamitsu Bando +2
We construct a minimal robust controlled-NOT gate with an Ising-type interaction by which elementary two-qubit gates are implemented. It is robust against inaccuracy of the couplin…
