Quantum information density scaling and qubit operation time constraints of CMOS silicon-based quantum computer architectures

Even the quantum simulation of an apparently simple molecule such as Fe2S2 requires a considerable number of qubits of the order of 106, while more complex molecules such as alanine (C3H7NO2) require about a hundred times more. In order to assess such a mu ...

Cryo-CMOS Circuits and Systems for Quantum Computing Applications

Edoardo Charbon, Harald Arjan Robert Homulle, Fabio Sebastiano

A fault-tolerant quantum computer with millions of quantum bits (qubits) requires massive yet very precise control electronics for the manipulation and readout of individual qubits. CMOS operating at cryogenic temperatures down to 4 K (cryo-CMOS) allows fo ...

Two-terminal transport measurements with cold atoms

Jean-Philippe Brantut

In recent years, the ability of cold atom experiments to explore condensed-matter-related questions has dramatically progressed. Transport experiments, in particular, have expanded to the point in which conductance and other transport coefficients can now ...

Higher order mode suppression in high-Q anomalous dispersion SiN microresonators for temporal dissipative Kerr soliton formation

Tobias Kippenberg, Victor Brasch, Hairun Guo, Martin Hubert Peter Pfeiffer, Arne Kordts

High-Q silicon nitride (SiN) microresonators enable optical Kerr frequency comb generation on a photonic chip and have recently been shown to support fully coherent combs based on temporal dissipative Kerr soliton formation. For bright soliton formation, i ...

Large-Scale Silicon Photonic Switches

Niels Quack

Large-scale (50x50 and 64x64) integrated photonic switches have been realized by combining silicon photonics with efficient micro-electro-mechanical-system (MEMS) switching mechanisms. Low on-chip loss (0.058dB/port) and sub-microsecond switching time have ...
