Advances in quantum dot intermediate band solar cells [PDF]

, 2010
Several groups have reported on intermediate band solar cells (IBSC) fabricated with InAs/GaAs quantum dots (QD) which exhibit quantum efficiencies (QE) for sub-bandgap photon energies.

Quantum circuit debugging and sensitivity analysis via local inversions [PDF]

Quantum, 2023
As the width and depth of quantum circuits implemented by state-of-the-art quantum processors rapidly increase, circuit analysis and assessment via classical simulation are becoming unfeasible. It is crucial, therefore, to develop new methods to identify

Quantum circuits for OR and AND of ORs [PDF]

Journal of Physics A: Mathematical and General, 2000
Summary: We give the first quantum circuit for computing \(f(0)\) OR \(f(1)\) more reliably than is classically possible with a single evaluation of the function. OR therefore joins XOR (i.e.

Superabsorption of light via quantum engineering [PDF]

, 2014
Almost 60 years ago Dicke introduced the term superradiance to describe a signature quantum effect: N atoms can collectively emit light at a rate proportional to N-2.

Superadiabatic population transfer in a three-level superconducting circuit [PDF]

, 2019
Adiabatic manipulation of the quantum state is an essential tool in modern quantum information processing. Here, we demonstrate the speedup of the adiabatic population transfer in a three-level superconducting transmon circuit by suppressing the spurious

Universal Quantum Circuits

Electron. Colloquium Comput. Complex., 2008
We define and construct efficient depth-universal and almost-size-universal quantum circuits. Such circuits can be viewed as general-purpose simulators for central classes of quantum circuits and can be used to capture the computational power of the circuit class being simulated.

Machine Learning of Noise-Resilient Quantum Circuits

PRX Quantum, 2021
Noise mitigation and reduction will be crucial for obtaining useful answers from near-term quantum computers. In this work, we present a general framework based on machine learning for reducing the impact of quantum hardware noise on quantum circuits ...

Quantum key recovery attack on SIMON32/64

Cybersecurity, 2021
The quantum security of lightweight block ciphers is receiving more and more attention. However, the existing quantum attacks on lightweight block ciphers only focused on the quantum exhaustive search, while the quantum attacks combined with classical ...

Many Worlds, the Cluster-state Quantum Computer, and the Problem of the Preferred Basis [PDF]

, 2011
I argue that the many worlds explanation of quantum computation is not licensed by, and in fact is conceptually inferior to, the many worlds interpretation of quantum mechanics from which it is derived. I argue that the many worlds explanation of quantum

Quantum interference and manipulation of entanglement in silicon wire waveguide quantum circuits [PDF]

, 2012
Integrated quantum photonic waveguide circuits are a promising approach to realizing future photonic quantum technologies. Here, we present an integrated photonic quantum technology platform utilizing the silicon-on-insulator material system, where ...
