Symmetric Universal Quantum Cloning Machine (UQCM) N --> M for unknown states

Does it exist a schematic diagram of the quantum circuit implementing the symmetric UQCM N--> M for unknown states? If yes, does anyone know a Qiskit implementation of it?...

What are the pros/cons of Trapped Ion Qubits, Superconducting Qubits and Si Spin Qubits?

Among available qubit technologies for universal quantum computing these 3 come up as promising. NV centers and Majorana qubits also underway but relatively new.I find superconducting qubits and Trapped...

Average execution time for T gate

Using the Q# resource estimator, I found out that my program, meant to do graph coloring using Grover's algorithm, could be decomposed into ~500-1000*x T gates, where x in the...

A question about Grover's paper "Fixed-Point Quantum Search"

I am reading Grover's paper "Fixed-Point Quantum Search," (arXiv version with a different name) which improves on his earlier quantum research algorithm. However, I'm...

How can you decompose Grover's diffusion operator into gates?

I know how Grover's diffusion operator works ($U_s = 2|sranglelangle s|-I$) with the inversion around the mean. However, I want to implement it in simpler gates, to use the...

How can the entropy of quantum states increase after projective measurements?

I'm reading Nielsen and chuang 11.3.3 Measurements and Entropy.It says after measurement, one's entropy increases.How is this possible? Shouldn't measurement decrease one's uncertainty?...

Constructing and Measuring in an Arbitrary 3-qubit basis

As part of a Quantum Theory project I have "constructed" an arbitrary 3-qubit basis: $left|B_0right> =left|000right>$ $left|B_1right> = frac{1}{sqrt{2}}cos(x)(left|100right> + left|010right>) + sin(x)left|001right>$ and so on to...

Relation between Jordan-Wigner transformation and Hilbert-Schmidt inner product

Given a fermionic Hamiltonian in a matrix form, we can write it as a sum over Kronecker products of Pauli matrices using the Hilbert-Schmidt inner product. However if the same...
