Quantum orders in an exact soluble model
... are described by their ground state wave functions which are complex functions of infinite variables. Thus it is not surprising that FQH states contain addition structures (or a new kind of orders) that cannot be described by broken symmetries and the Landau’s theory. From this point of view, we see ...

How to test the “quantumness” of a quantum computer? Miroslav Grajcar
... The looming impossibility to predict the behavior of any big enough quantum processor (adiabatic, gate-based, etc) and even to test it for “quantumness” using classical tools, is the elephant in the room, and it may effectively restrict any further progress. Even taking the optimistic view, that qua ...

Topological Quantum Computing
... such algorithm stores the quantum information redundantly, so that the information of one logical qubit is stored in three qubits. That is, the state that used to be described as, ψ = a | 0i + b | 1i is now described by ψ = a | 000i + b | 111i, with each number representing an individual qubit. Let ...

Enhancement of quantum dot peak-spacing fluctuations
... potential fluctuations do not mix in excited states (i.e. when the potential energy is smaller than the gap), the peak-spacing fluctuations (PSF) can be evaluated as expectation values in the Laughlin state. As such expectation values can be easily calculated using the plasma analogy [7], via, e.g., ...

A functional quantum programming language

We can also easily calculate that applying had twice gets us back where we started by cancelling out amplitudes. An important feature of quantum programming is the possibility to crea ...
