The Complexity of Dynamical Correlators: Operator Shadows and Exponential Learning Separations
Shao-Hen Chiew, Armando Angrisani, Zoe Holmes
Quantum platforms can realize many-body dynamics beyond classical simulation yet complete readout remains intractable: the cost of extracting accessible information scales exponent…
Quantum simulation in the Heisenberg picture via vectorization
Shao-Hen Chiew, Armando Angrisani, Zoë Holmes +1
We present a general framework for simulating quantum systems in the Heisenberg picture on quantum hardware. Based on the vectorization map, our framework fully exploits the mappin…
Information-efficient decoding of surface codes
Long D. H. My, Shao-Hen Chiew, Jing Hao Chai +1
Surface codes are a popular error-correction route to fault-tolerant quantum computation. The so-called exponential backlog problem that can arise when one has to do logical -ga…
Fault-tolerant embedding of quantum circuits on hardware architectures via swap gates
Shao-Hen Chiew, Ezequiel Ignacio Rodriguez Chiacchio, Vishal Sharma +2
In near-term quantum computing devices, connectivity between qubits remain limited by architectural constraints. A computational circuit with given connectivity requirements necess…
Multi-Objective Optimization and Network Routing with Near-Term Quantum Computers
Shao-Hen Chiew, Kilian Poirier, Rajesh Mishra +6
Multi-objective optimization is a ubiquitous problem that arises naturally in many scientific and industrial areas. Network routing optimization with multi-objective performance de…
Scalable Quantum Computation of Highly Excited Eigenstates with Spectral Transforms
Shao-Hen Chiew, Leong-Chuan Kwek
We propose a natural application of Quantum Linear Systems Problem (QLSP) solvers such as the HHL algorithm to efficiently prepare highly excited interior eigenstates of physical H…
OpenQAOA -- An SDK for QAOA
Vishal Sharma, Nur Shahidee Bin Saharan, Shao-Hen Chiew +4
We introduce OpenQAOA, a Python open-source multi-backend Software Development Kit to create, customise, and execute the Quantum Approximate Optimisation Algorithm (QAOA) on Noisy…
Improving sum uncertainty relations with the quantum Fisher information
Shao-Hen Chiew, Manuel Gessner
We show how preparation uncertainty relations that are formulated as sums of variances may be tightened by using the quantum Fisher information to quantify quantum fluctuations. We…
Stability and Dynamics of Many-Body Localized Systems Coupled to Small Bath
Shao-Hen Chiew, Jiangbin Gong, Leong-Chuan Kwek +1
It is known that strong disorder in closed quantum systems leads to many-body localization (MBL), and that this quantum phase can be destroyed by coupling to an infinitely large Ma…
Fourth-order leapfrog algorithms for numerical time evolution of classical and quantum systems
Jun Hao Hue, Ege Eren, Shao Hen Chiew +5
Chau et al. [New J. Phys. 20, 073003 (2018)] presented a new and straight-forward derivation of a fourth-order approximation '' of the time-evolution operator and hinted at it…
