Detecting bit-flip errors in a logical qubit using stabilizer measurements
D. Ristè, S. Poletto, M. -Z. Huang +4
Quantum data is susceptible to decoherence induced by the environment and to errors in the hardware processing it. A future fault-tolerant quantum computer will use quantum error c…
Josephson junction microwave amplifier in self-organized noise compression mode
Pasi Lähteenmäki, Visa Vesterinen, Juha Hassel +2
The fundamental noise limit of a phase-preserving amplifier at frequency is the standard quantum limit . In the microwave range, the best candidates ha…
Advanced Concepts in Josephson Junction Reflection Amplifiers
Pasi Lähteenmäki, Visa Vesterinen, Juha Hassel +3
Low-noise amplification atmicrowave frequencies has become increasingly important for the research related to superconducting qubits and nanoelectromechanical systems. The fundamen…
Mitigating information leakage in a crowded spectrum of weakly anharmonic qubits
V. Vesterinen, O. -P. Saira, A. Bruno +1
A challenge for scaling up quantum processors using frequency-crowded, weakly anharmonic qubits is to drive individual qubits without causing leakage into non-computational levels…
Kinetic Inductance Magnetometer
Juho Luomahaara, Visa Vesterinen, Leif Grönberg +1
Ultrasensitive magnetic field detection is utilized in the fields of science, medicine and industry. We report on a novel magnetometer relying on the kinetic inductance of supercon…
