A Lattice Problem in Quantum NP
We consider coGapSV P√ n, a gap version of the shortest vector in a lattice problem. This problem is known to be in AM ∩coNP but is not known to be in NP or in MA. We prove th...

Private Quantum Channels
Shannon [Sha48, Sha49] in celebrated works had shown that n bits of shared key is necessary and sufficient to transmit n-bit classical information in an information-theoretically ...

The Quantum Black-Box Complexity of Majority
We describe a quantum black-box network computing the majority of N bits with zerosided error using only 2 3 N + O( N log( -1 log N)) queries: the algorithm returns the correct an...

On the Efficiency of Classical and Quantum Oblivious Transfer Reductions
Due to its universality oblivious transfer (OT) is a primitive of great importance in secure multi-party computation. OT is impossible to implement from scratch in an unconditional...

Testing of Quantum Dot Cellular Automata Based Designs
There has been considerable research on quantum dots cellular automata as a new computing scheme in the nano-scale regimes. The basic logic element of this technology is a majorit...
