Classical Shadows with Improved Median-of-Means Estimation
Winston Fu, Dax Enshan Koh, Siong Thye Goh +1
The classical shadows protocol, introduced by Huang et al. [Nat. Phys. 16, 1050 (2020)], makes use of the median-of-means (MoM) estimator to efficiently estimate the expectation va…
Analytical Expressions for the Quantum Approximate Optimization Algorithm and its Variants
Truman Yu Ng, Jin Ming Koh, Dax Enshan Koh
The quantum approximate optimization algorithm (QAOA) is a near-term quantum algorithm aimed at solving combinatorial optimization problems. Since its introduction, various general…
Quantum Volunteer's Dilemma
Dax Enshan Koh, Kaavya Kumar, Siong Thye Goh
The volunteer's dilemma is a well-known game in game theory that models the conflict players face when deciding whether to volunteer for a collective benefit, knowing that voluntee…
Pseudorandom density matrices
Nikhil Bansal, Wai-Keong Mok, Kishor Bharti +2
Pseudorandom states (PRSs) are state ensembles that cannot be efficiently distinguished from Haar random states. However, the definition of PRSs has been limited to pure states and…
Communication with Quantum Catalysts
Yuqi Li, Junjing Xing, Dengke Qu +8
Communication is essential for advancing science and technology. Quantum communication, in particular, benefits from the use of catalysts. During the communication process, these c…
Teleportation with Embezzling Catalysts
Junjing Xing, Yuqi Li, Dengke Qu +7
Quantum teleportation is the process of transferring quantum information using classical communication and pre-shared entanglement. This process can benefit from the use of catalys…
Solving Fractional Differential Equations on a Quantum Computer: A Variational Approach
Fong Yew Leong, Dax Enshan Koh, Jian Feng Kong +6
We introduce an efficient variational hybrid quantum-classical algorithm designed for solving Caputo time-fractional partial differential equations. Our method employs an iterable…
Readout Error Mitigation for Mid-Circuit Measurements and Feedforward
Jin Ming Koh, Dax Enshan Koh, Jayne Thompson
Current quantum computing platforms suffer from readout errors, where faulty measurement outcomes are reported by the device. These errors are particularly harmful in quantum progr…
Towards enhancing quantum expectation estimation of matrices through partial Pauli decomposition techniques and post-processing
Dingjie Lu, Yangfan Li, Dax Enshan Koh +3
We introduce an approach for estimating the expectation values of arbitrary -qubit matrices on a quantum computer. In contrast to conventional…
