About marcocerezo

I'm Marco Cerezo, I have a Ph.D in Physics and I'm currently a Postdoctoral Research Associate at Los Alamos National Laboratory in New Mexico, USA. My main fields of study are Quantum Information, Quantum Computing and Condensed Matter. Currently I'm working to develop novel quantum algorithms which can be useful in near-term quantum devices.

The More You Know: Bell States/EPR Pairs

Bell States (named after John S. Bell) or EPR pairs (after Einsetin, Podolski and Rosen Paradox) are the maximally entangled quantum states of a two qubit system (i.e. a quantum mechanical system composed of two interacting two-level subsystems). In the computational basis  the four … Continue reading

The More You Know: Bloch Sphere

The Bloch Sphere is a useful geometrical representation of the state of a Qubit or any other two level quantum system. As discussed in this article an arbitrary pure state of a Qubit can be expressed in the computational basis as … Continue reading

The More You Know: Loss-DiVicenzo Quantum Computer

The Loss-DiVicenzo Quantum Computer is a hardware proposal for the implementation of a scalable spin-based quantum computer in a coupled quantum dot system. The qubits of their quantum computer are realized as the two spin states of a confined electron. In … Continue reading

The More You Know: EPR Paradox

The EPR Paradox is a thought experiment published in a paper in May 1935 by Albert Einstein and two of his postdoctoral research associates Boris Podolsky and Nathan Rosen that was meant to prove that Quantum Mechanics showed internal contradictions in it’s … Continue reading

The More You Know: DiVicenzo Criteria

The DiVicenzo Criteria for implementing a quantum computer are a set of requirements that any candidate (circuit model) quantum computer must satisfy. These five requirements, plus two relating to the communication of quantum information were formulated by David P. DiVincenzo in 2008 and are … Continue reading

The More You Know: Boson Sampling

Boson Sampling is a model for non-universal quantum computation which performs specific tasks that are thought to be hard to efficiently perform on a classical computer. By exploiting the processing power of quantum mechanics, the output photon number distribution of … Continue reading
