Efficient Quantum Simulation of Variable-Coefficient Transport with Continuous Source Injection
Mohammad Mehedi Hasan Akash, Turag Dev, Nhat-Quang Nguyen +3
Quantum time-marching algorithms for transport PDEs often represent variable coefficients and forcing through register-expanding dilations, block-encoding oracles, or repeated post…
Hybrid Lattice Surgery: Non-Clifford Gates via Non-Abelian Surface Codes
Sheng-Jie Huang, Alison Warman, Sakura Schafer-Nameki +1
In universal fault-tolerant quantum computing, implementing logical non-Clifford gates often demands substantial spacetime resources for many error-correcting codes, including the…
Generating logical magic states with the aid of non-Abelian topological order
Sheng-Jie Huang, Yanzhu Chen
In fault-tolerant quantum computing with the surface code, non-Clifford gates are crucial for universal computation. However, implementing these gates using methods like magic stat…
Detector Tomography on IBM 5-qubit Quantum Computers and Mitigation of Imperfect Measurement
Yanzhu Chen, Maziar Farahzad, Shinjae Yoo +1
We use quantum detector tomography to characterize the qubit readout in terms of measurement POVMs on IBM Quantum Computers IBM Q 5 Tenerife and IBM Q 5 Yorktown. Our results sugge…
Quantum algorithm for spectral projection by measuring an ancilla iteratively
Yanzhu Chen, Tzu-Chieh Wei
We propose a quantum algorithm for projecting a quantum system to eigenstates of any Hermitian operator, provided one can access the associated control-unitary evolution for the an…
