# Towards Minimal Resources of Measurement-based Quantum Computation

## TL;DR

This paper establishes a tighter upper bound on the minimal resources needed for measurement-based quantum computation, advancing understanding of resource efficiency and resolving a key open question about qubit trade-offs.

## Contribution

It provides a new upper bound on resources for measurement-based quantum computation and addresses the trade-off between observable and ancillary qubits.

## Key findings

- New upper bound on minimal resources for measurement-based quantum computation
- Negative answer to the open question about observable-ancillary qubits trade-off
- Implications for experimental realization of quantum computers

## Abstract

We improve the upper bound on the minimal resources required for measurement-based quantum computation. Minimizing the resources required for this model is a key issue for experimental realization of a quantum computer based on projective measurements. This new upper bound allows also to reply in the negative to the open question about the existence of a trade-off between observable and ancillary qubits in measurement-based quantum computation.
