Five-qubit states generated by Clifford gates
Frederic Latour, Oscar Perdomo
The Clifford group is the set of gates generated by controlled-Z gates, the phase gate and the Hadamard gate. We will say that a n-qubit state is a Clifford state if it can be prep…
Preparation of 3-qubit states
Oscar Perdomo, Nelson Castaneda, Roger Vogeler
We will call a pure qubit state real if all its amplitudes are real numbers. We show that any real 3-qubit state can be prepared using gates and at most four controlled-$Z…
Schmidt representation of 3-qubits with real amplitudes
Oscar Perdomo
From the Schmidt representation we have that, up to local gates, every 2-qubit state can be written as with and real numbers.…
Controlled not connectivity in the Clifford group
Oscar Perdomo, Reilly Ratcliffe
The Clifford group is the set of gates generated by the CZ gate, and the two local gates: the Hadamard and the Pi/2 phase shift gate. It is known that, for a two qubit system, the…
Four qubits generated by Clifford gates
Frederic Latour, Oscar Perdomo
The Clifford group is the set of gates generated by the controlled not gates, the Hadamard gate and the P={{1,0},{0,i}} gate. We will say that a n-qubit state is a Clifford state i…
Partition of 3-qubits using local gates
Oscar Perdomo
It is well known that local gates have smaller error than non-local gates. For this reason it is natural to make two states equivalent if they differ by a local gate. Since two sta…
