Quantum Journal Club: Speed Optimized Two-Qubit Gates with Laser Coherent Contro
Abstract: We propose a new concept for a two-qubit gate operating on a pair of trapped ions based on laser coherent control techniques. The gate is insensitive to the temperature of the ions, works a...

Entanglement detection length of multipartite quantum states
Abstract: Multipartite entanglement is a crucial resource for quantum computing, communication, and metrology. However, detecting this resource can be challenging: for genuine multipartite entangleme...

Quantum Journal Club: Experimental verification of Landauer's principle linking information and thermodynamics
Abstract: In 1961, Rolf Landauer argued that the erasure of information is a dissipative process1.Aminimal quantity of heat, proportional to the thermal energy and called the Landauer bound, is neces...

Precision measurements with trapped ion and development of a surface ion trap setup
Abstract: I will discuss lifetime measurement of SF^{-}_{6} measured with an unprecedented precision. The electron affinity thus extracted soundly establishes the structure of an SF^{-}_{6} molecular...

Probabilistic simulations of quantum communication backward in time
Abstract: Like classical mechanics, quantum mechanics is a causal theory [1,2]--a theory that forbids sending messages from the future to the past. Still, one can simulate backward communication by p...

Schrödinger-Heisenberg Variational Quantum Algorithms
Abstract: Recent breakthroughs have opened the possibility to intermediate-scale quantum computing with tens to hundreds of qubits, and shown the potential for solving classical challenging problems,...
