Optical quantum communication complexity in the simultaneous message passing model
Ashutosh Marwah, Dave Touchette
The communication cost of a classical protocol is typically measured in terms of the number of bits communicated for this determines the time required for communication during the…

Erasable Bit Commitment from Temporary Quantum Trust
Norbert Lütkenhaus, Ashutosh S Marwah, Dave Touchette
We introduce a new setting for two-party cryptography with temporarily trusted third parties. In addition to Alice and Bob in this setting, there are additional third parties, whic…

Characterization of Gram matrices of multimode coherent states
Ashutosh S Marwah, Norbert Lütkenhaus
Quantum communication protocols are typically formulated in terms of abstract qudit states and operations, leaving the question of an experimental realization open. Direct translat…
