Finding good quantum codes using the Cartan form
Akshaya Jayashankar, Anjala M Babu, Hui Khoon Ng +1
We present a simple and fast numerical procedure to search for good quantum codes for storing logical qubits in the presence of independent per-qubit noise. In a key departure from…
User-specified random sampling of quantum channels and its applications
Jun Yan Sim, Jun Suzuki, Berthold-Georg Englert +1
Random samples of quantum channels have many applications in quantum information processing tasks. Due to the Choi--Jamiołkowski isomorphism, there is a well-known correspondence b…
Quantum process tomography via optimal design of experiments
Yonatan Gazit, Hui Khoon Ng, Jun Suzuki
Quantum process tomography --- a primitive in many quantum information processing tasks --- can be cast within the framework of the theory of design of experiment (DoE), a branch o…
Proper error bars for self-calibrating quantum tomography
Jun Yan Sim, Jiangwei Shang, Hui Khoon Ng +1
Self-calibrating quantum state tomography aims at reconstructing the unknown quantum state and certain properties of the measurement devices from the same data. Since the estimates…
Reply to "Comment on `Past of a quantum particle revisited' "
Berthold-Georg Englert, Kelvin Horia, Jibo Dai +2
We stand by our findings in Phys. Rev A. 96, 022126 (2017). In addition to refuting the invalid objections raised by Peleg and Vaidman, we report a retrocausation problem inherent…
