- Abstract summary: We present an entanglement-free alternative that has advantages in terms of simplicity and practicality, requiring only individual qubits to be transmitted.
We demonstrate the performance of the scheme in both the low and high data limits, showing quantum advantages both in terms of measurement precision and security against a range of possible attacks.

- Abstract: Quantum metrology and quantum communications are typically considered as
distinct applications in the broader portfolio of quantum technologies.
However, there are cases where we might want to combine the two and recent
proposals have shown how this might be achieved in entanglement-based systems.
Here we present an entanglement-free alternative that has advantages in terms
of simplicity and practicality, requiring only individual qubits to be
transmitted. We demonstrate the performance of the scheme in both the low and
high data limits, showing quantum advantages both in terms of measurement
precision and security against a range of possible attacks.

We propose a quantum illumination network to overcome the limitations, via designing a transmitter array and a single receiver antenna.
Thanks to multiple transmitters, quantum advantage is achieved even with a high total transmitted power.
We generalize the parameter estimation scenario to a general hypothesis testing scenario, where the six-decibel quantum illumination advantage is achieved at a much greater total probing power.

We develop a framework for quantum resource estimation, abstracting the layers of the stack, to estimate resources required for large-scale quantum applications.
We assess three scaled quantum applications and find that hundreds of thousands to millions of physical qubits are needed to achieve practical quantum advantage.
A goal of our work is to accelerate progress towards practical quantum advantage by enabling the broader community to explore design choices across the stack.

We present an approach where the quantum computation is supplemented by a classical result.
Taking advantage of its anticipation also leads to a new type of quantum measurements, which we call anticipative.
In an anticipative quantum measurement the combination of the results from classical and quantum computations happens only in the end.
