Applications beyond QKD in QNE
In the last video, we have introduced an application called quantum key distribution (QKD). In this video, we will cover two other applications of quantum networks in QNE. The applications that we’ll discover today are Quantum state teleportations and Blind Quantum Computing (BQC). We will cover what there applications are, why we care about them and how they work.
Main takeaways
- We cannot copy arbitrary quantum states: this is the no-cloning theorem.
- We can send a possibly unknown quantum state to a remote receiver using quantum state teleportation.
- Teleportation works by using entangled photon pairs and making measurements.
- We can perform quantum computations at a remote quantum server to scale up quantum computing usage.
- Using Blind Quantum Computing (BQC), we can perform a remote computation without revealing the input, computation and output to the server.
- In BQC, a client performs remote state preparation at the server, who will then use measurement-based quantum computing to perform the computation.
