We present a detailed study of portfolio optimization using different versions of the quantum approximate optimization algorithm (QAOA). For a given list of assets, the portfolio …

We present short-depth quantum circuits to deterministically prepare any Dicke state \left|D_k^n\right⟩, which is the equal-amplitude superposition of all n-qubit computational …
Near-term quantum computers are limited by the decoherence of qubits to only being able to run low-depth quantum circuits with acceptable fidelity. This severely restricts what quantum …
We present a divide-and-conquer approach to deterministically prepare Dicke states (ie, equal-weight superpositions of all-qubit states with Hamming weight) on quantum …
This paper proposes an asymmetric tridirectional quantum teleportation (TQT) protocol that uses a seven-qubit cluster states as the quantum channels of each party. In this scheme, any …

Recently, an algorithm has been constructed that shows that the binary icosahedral group 2I together with a T-like gate forms the most efficient single-qubit universal gate set. To carry …
Quantum state preparation is a key step in all digital quantum simulation algorithms. Here we propose methods to initialize on a gate-based quantum computer a general class of …
The antisymmetrized geminal power (AGP) is equivalent to the number projected Bardeen– Cooper–Schrieffer (PBCS) wave function. It is also an elementary symmetric polynomial …
We construct a new family of permutationally invariant codes that correct $ t $ Pauli errors for any $ t\ge 1$. We also show that codes in the new family correct quantum deletion errors as …
