Superadiabatic population transfer in a three-level superconducting circuit

Antti Vepsäläinen, Sergey Danilin, Gheorghe Sorin Paraoanu

Adiabatic manipulation of the quantum state is an essential tool in modern quantum information processing. Here we demonstrate the speed-up of the adiabatic population transfer in…

Speeding-up a quantum refrigerator via counter-diabatic driving

Ken Funo, Neill Lambert, Bayan Karimi +3

We study the application of a counter-diabatic driving (CD) technique to enhance the thermodynamic efficiency and power of a quantum Otto refrigerator based on a superconducting qu…

Optimal superadiabatic population transfer and gates by dynamical phase corrections

A. Vepsäläinen, S. Danilin, G. S. Paraoanu

In many quantum technologies adiabatic processes are used for coherent quantum state operations, offering inherent robustness to errors in the control parameters. The main limitati…

Calibration of cryogenic amplification chains using normal-metal--insulator--superconductor junctions

Eric Hyyppä, Máté Jenei, Shumpei Masuda +7

Various applications of quantum devices call for an accurate calibration of cryogenic amplification chains. To this end, we present a convenient calibration scheme and use it to ac…

Non-Local Parity Measurements and the Quantum Pigeonhole Effect

G. S. Paraoanu

The pigeonhole principle upholds the idea that by ascribing to three different particles either one of two properties, we necessarily end up in a situation when at least two of the…
