Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Quantum Error Correction: Foundation and Landscape
量子纠错 基础景观 量子纠错理论
2023/4/18
Quantum error correction theory lies at the heart of universal quantum computing. So far, people do not find or realize good-enough error correction codes yet. In this talk, I will survey the foundati...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Quantum Error Correction: Fault-tolerance and Universality

2023/4/17
There is a big gap between the so-called NISQ (noisy intermediate-scale quantum) and FTQ (fault-tolerant quantum) computing. Recently, we introduced QEQ (quasi-exact quantum) computing, which lies in ...
INSAR UNWRAPPING ERROR CORRECTION BASED ON QUASI-ACCURATE DETECTION OF GROSS ERRORS (QUAD)
QUAD, InSAR, Unwrapping Error Correction, Gross Error, L1-norm
2018/5/14
Unwrapping error is a common error in the InSAR processing, which will seriously degrade the accuracy of the monitoring results. Based on a gross error correction method, Quasi-accurate detection (QUA...
"HILA5 Pindakaas": On the CCA security of lattice-based encryption with error correction
Post-quantum cryptography KEM RLWE
2017/12/19
We show that HILA5 is not secure against chosen-ciphertext attacks. Specifically, we demonstrate a key-recovery attack on HILA5 using an active attack on reused keys. The attack works around the error...
On Reliability, Reconciliation, and Error Correction in Ring-LWE Encryption
Ring-LWE Reconciliation Post-Quantum Encryption
2017/5/23
We describe a new reconciliation method for Ring-LWE that has a significantly smaller failure rate than previous proposals while reducing ciphertext size and the amount of randomness required. It is b...

physical unclonable function error correction key reconciliation
2016/12/8
Physical Unclonable Functions (PUFs) are promising primitives for lightweight integrated circuit authentication. Indeed, by extracting an identifier from random process variations, they allow each ins...
Ring-LWE Ciphertext Compression and Error Correction: Tools for Lightweight Post-Quantum Cryptography
Practical Post-Quantum Cryptography Lattice Cryptography Ring-LWE
2016/12/7
Some lattice-based public key cryptosystems allow one to transform ciphertext from one lattice or ring representation to another efficiently and without knowledge of public and private keys. In this w...
Applying Cryptographic Acceleration Techniques to Error Correction
polynomial Barrett BCH error correcting codes
2015/12/23
Modular reduction is the basic building block of many publickey
cryptosystems. BCH codes require repeated polynomial reductions
modulo the same constant polynomial. This is conceptually very similar...

2015/6/17
This paper discusses a stylized communications problem where one wishes to transmit a real-valued signal x ∈ Rn (a block of n pieces of information) to a remote receiver. We ask whether it is possible...

2015/6/17
Suppose we wish to transmit a vector f ∈ Rn reliably. A frequently discussed approach consists in encoding f with an m by n coding matrix A. Assume now that a fraction of the entries of Af are corrupt...

2015/6/17
We consider the problem of recovering a lowrank matrix when some of its entries, whose locations are not known a priori, are corrupted by errors of arbitrarily large magnitude. It has recently been sh...
