Abstract:

What can part ies achieve when they interact with one another using quantum information- resources\, that is impossible classically?
I introduce a quantum inf ormation–theoretic primitive for determining a discrete-valued function that depends on multiple parties’ local private inputs.

The p rimitive permits the parties to mutually learn each others' local inputs\, and thereby determine function values\, while their individual systems re main independent of these inputs. The resulting function values are shared among the parties\, but may remain information-theoretically hidden from any external observer\, as well as from adversarial state-preparation or m easurement processes within the quantum system\, in every iteration.

In particular\, while classically producing a shared function with t hese information-theoretic properties requires the use of private keys or hidden randomness\, in the proposed setting it is achieved using entanglem ent alone -- permitting a quantum computational capability with no classic al counterpart.

I'll discuss the primitive's general properties and applications across a broad range of secure quantum communication and computation settings including\; quantum key distribution\, multi-party c oordination and decision schemes\, function evaluation\, and in some setti ngs\, protocols for fairly generated private coins.

Olivia Hartzell is an independent researcher working at the intersect ion of quantum information\, communication\, and quantum games. Her work e xplores how quantum-mediated interactions depart from classical counterpar ts. She holds a PhD from Harvard University\, where her research focused o n structural estimation of game-theoretic models and mechanism design.
