A reconfigurable cryogenic platform for the classical control of quantum processors

Edoardo Charbon, Harald Arjan Robert Homulle, Fabio Sebastiano

The implementation of a classical control infrastructure for large-scale quantum computers is challenging due to the need for integration and processing time, which is constrained by coherence time. We propose a cryogenic reconfigurable platform as the hea ...

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

Edoardo Charbon, Fabio Sebastiano

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 ...

Nonlinear graphene quantum capacitors for electro-optics

Sina Khorasani, Akshay Koottandavida

Owing to its peculiar energy dispersion, the quantum capacitance property of graphene can be exploited in a two- dimensional layered capacitor configuration. Using graphene and boron nitride, respectively, as the electrodes and the insulating dielectric, a ...

A dissipative quantum reservoir for microwave light using a mechanical oscillator

Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth

Isolation of a system from its environment is often desirable, from precision measurements to control of individual quantum systems; however, dissipation can also be a useful resource. Remarkably, engineered dissipation enables the preparation of quantum s ...
