D3$ifru7 - šifrovacia hra v rámci Európskej noci výskumníkov 2018
In collaboration with organizers of European Researcher's Night 2018 we have designed a cipher game competition. Do you want to try? Let us help you that ciphers are in Slovak language. Let's play with us. Are you more than 16 years old? Age is just a number, but if you are below 16, your chances are a bit smaller. We are seeking for best candidate.
[img] 8.6.2018 Publication Shorter unentangled proofs for ground state connectivity
Can one considerably shorten a proof for a quantum problem by using a protocol with a constant number of unentangled provers? We consider a frustration-free variant of the QCMA -complete ground state connectivity (GSCON) problem for a system of size n with a proof of superlinear size. We show that we can shorten this proof in QMA(2): There exists a two-copy, unentangled proof with length of order n, up to logarithmic factors, while the completeness–soundness gap of the new protocol becomes a small inverse polynomial in n.
