Variational approach to time-dependent fluorescence of a driven qubit
We employ the Dirac-Frenkel variational principle and the multiple Davydov ansatz to study time-dependent fluorescence spectra of a driven qubit in the weak to strong qubit-reservoir coupling regimes, where both the Rabi frequency and the spontaneous decay ...
AMER PHYSICAL SOC2020Characterization and Analysis of On-Chip Microwave Passive Components at Cryogenic Temperatures
Edoardo Charbon, Andrea Ruffino, Fabio Sebastiano
This paper presents the characterization and modeling of microwave passive components in TSMC 40-nm bulk CMOS, including metal-oxide-metal (MoM) capacitors, transformers, and resonators, at deep cryogenic temperatures (4.2 K). To extract the parameters of ...
2020Optical-Microwave Pump-Probe Studies of Electronic Properties in Novel Materials
Ferenc Simon, Karoly Holczer, Bence Gábor Márkus, Sándor Kollarics, András Bojtor
Combined microwave-optical pump-probe methods are emerging to study the quantum state of spin qubit centers and the charge dynamics in semiconductors. A major hindrance is the limited bandwidth of microwave irradiation/detection circuitry which can be over ...
WILEY-V C H VERLAG GMBH2020Benefits and Challenges of Designing Cryogenic CMOS RF Circuits for Quantum Computers
Edoardo Charbon, Harald Arjan Robert Homulle, Fabio Sebastiano
Accurate and low-noise generation and amplification of microwave signals are required for the manipulation and readout of quantum bits (qubits). A fault-tolerant quantum computer operates at deep cryogenic temperatures (i.e.,
IEEE2019Coherent microwave-photon-mediated coupling between a semiconductor and a superconducting qubit
Semiconductor qubits rely on the control of charge and spin degrees of freedom of electrons or holes confined in quantum dots. They constitute a promising approach to quantum information processing, complementary to superconducting qubits. Here, we demonst ...
2019The electronic interface for quantum processors
Edoardo Charbon, Fabio Sebastiano
Quantum computers can potentially provide an unprecedented speed-up with respect to traditional computers. However, a significant increase in the number of quantum bits (qubits) and their performance is required to demonstrate such quantum supremacy. While ...
