Leakage benchmarking with decohering subgroups in the presence of preparation and measurement errors

Shawn Geller, Tongyu Zhao, Alex Kwiatkowski +3

A common problem with physical qubits is that the state can leak outside the computational subspace. To characterize the problem, it is desirable to measure both the leakage probab…

Constraints on recovering quantum information after erasure

Mohammad A. Alhejji, Noah Lordi, Omkar Baraskar +2

Suppose that we encode quantum information into physical carriers. With what probabilities can we perfectly recover the quantum information after sets of carriers have been e…

An efficient method for spot-checking quantum properties with sequential trials

Yanbao Zhang, Akshay Seshadri, Emanuel Knill

In practical situations, the reliability of quantum resources can be compromised due to complex generation processes or adversarial manipulations during transmission. Consequently,…

Quantum Position Verification with Remote Untrusted Devices

Gautam A. Kavuri, Yanbao Zhang, Abigail R. Gookin +16

Position information underpins many modern technologies, from navigation and timing to authentication and critical infrastructure. However, classical methods of proving that inform…

Traceable random numbers from a nonlocal quantum advantage

Gautam A. Kavuri, Jasper Palfree, Dileep V. Reddy +20

The unpredictability of random numbers is fundamental to both digital security and applications that fairly distribute resources. However, existing random number generators have li…

Threshold Accuracy for Quantum Computation

E. Knill, R. Laflamme, W. Zurek

We have previously (quant-ph/9608012) shown that for quantum memories and quantum communication, a state can be transmitted over arbitrary distances with error provided each ga…

Approximation by Quantum Circuits

E. Knill

In a recent preprint by Deutsch et al. [1995] the authors suggest the possibility of polynomial approximability of arbitrary unitary operations on qubits by 2-qubit unitary ope…
