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 …

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 …

Quantum metrology is a promising practical use case for quantum technologies, where
physical quantities can be measured with unprecedented precision. In lieu of quantum error …

Quantum deletions, which are harder to correct than erasure errors, occur in many realistic
settings. It is therefore pertinent to develop quantum coding schemes for quantum deletion …

With respect to the transversal gate group (an invariant of quantum codes), we demonstrate
that non-additive codes can outperform stabilizer codes. We do this by constructing spin …

We propose a theoretical approach for entangling two Dicke states in a periodic modulated
quantum system. By considering two qubit ensembles that are nonuniformly coupled to a …

We must protect inherently fragile quantum data to unlock the potential of quantum
technologies. A pertinent concern in schemes for quantum storage is their potential for near …

We present a Dicke state preparation scheme which uses global control of N spin qubits: our
scheme is based on the standard phase estimation algorithm, which estimates the …

This paper presents conditions for constructing permutation-invariant quantum codes for
deletion errors and provides a method for constructing them. Our codes include examples of …

Implementing robust quantum error correction (QEC) is imperative for harnessing the
promise of quantum technologies. We introduce a framework that takes $ any $ classical …
