Beyond the thermodynamic limit: finite-size corrections to state interconversion rates
Christopher T. Chubb, Marco Tomamichel, Kamil Korzekwa
Thermodynamics is traditionally constrained to the study of macroscopic systems whose energy fluctuations are negligible compared to their average energy. Here, we push beyond this…
Quantum attacks on Bitcoin, and how to protect against them
Divesh Aggarwal, Gavin K. Brennen, Troy Lee +2
The key cryptographic protocols used to secure the internet and financial transactions of today are all susceptible to attack by the development of a sufficiently large quantum com…
On converse bounds for classical communication over quantum channels
Xin Wang, Kun Fang, Marco Tomamichel
We explore several new converse bounds for classical communication over quantum channels in both the one-shot and asymptotic regimes. First, we show that the Matthews-Wehner meta-c…
Non-asymptotic entanglement distillation
Kun Fang, Xin Wang, Marco Tomamichel +1
Entanglement distillation, an essential quantum information processing task, refers to the conversion from multiple copies of noisy entangled states to a smaller number of highly e…
Beating the Classical Limits of Information Transmission using a Quantum Decoder
Robert J. Chapman, Akib Karim, Zixin Huang +3
Encoding schemes and error-correcting codes are widely used in information technology to improve the reliability of data transmission over real-world communication channels. Quantu…
Quantum Sphere-Packing Bounds with Polynomial Prefactors
Hao-Chung Cheng, Min-Hsiu Hsieh, Marco Tomamichel
We study lower bounds on the optimal error probability in classical coding over classical-quantum channels at rates below the capacity, commonly termed quantum sphere-packing bound…
