Q-MERGE: Parallelising Quantum State Preparation for Large-Scale Classical Data
Archie Butterworth, Jens Renders, Jingbo Wang
Quantum processing of classical data fundamentally relies on efficiently mapping classical datasets onto the amplitudes of quantum states. Preparing large amplitude-encoded states,…
Efficient quantum state preparation on Quantinuum hardware
Archie Butterworth, Josh Green, Yusen Wu +2
Preparation and verification of specific quantum states is an important capability for quantum devices to realise advantages over classical computations and algorithms. In this wor…
Quantum State Preparation via Schmidt Spectrum Optimisation
Josh Green, Joshua Snow, Jingbo B Wang
Quantum state preparation represents a critical bottleneck for a broad class of quantum algorithms. In this work, we introduce the Schmidt Spectrum Optimisation (SSO) algorithm as…
Quantum Encoding of Structured Data with Matrix Product States
Josh Green, Jingbo B Wang
The amplitude encoding of an arbitrary -qubit state vector requires gate operations, owing to the exponential dimension of the Hilbert space. We can, however, form dime…
