The More You Know: Quantum Simulator
A Quantum Simulator is a controllable quantum mechanical system than can be used to study more complex quantum system that cannot be directly studied nor simulated by any classical computer. One of the most important consequences of the existence of … Continue reading
The More You Know: Quantum Circuit
Quantum Circuits are used to visualize a prescription of quantum gates acting on a quantum state. They describe the changes of the quantum data as it undergoes successive discrete operations. The data in a Quantum Circuit is usually encoded in a qubit state (other Quantum Circuit … Continue reading

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 twolevel 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: Qubit
A Qubit, or quantum bit is the fundamental unit of quantum information, it is a mathematical concept satisfying particular properties. The Qubit is the quantum counterpart of the classical bit. A classical bit can be in one of two different states: 0 … Continue reading

The More You Know: LossDiVicenzo Quantum Computer
The LossDiVicenzo Quantum Computer is a hardware proposal for the implementation of a scalable spinbased 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: Boson Sampling
Boson Sampling is a model for nonuniversal 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
