- As a community, QuantumComputingIndia is committed to learning through theory and practise and one such enabler is our #FaciltatorSeries where we invite exceptional academicians and Practitioners to share their knowledge with the community. As a part of this ongoing series we had Dr. Urbasi with us last saturday and this is quick log of the knowledge shared by Dr. Urbasi around Qauntum Communications and the state of such research initiatives in India.
The different ways in which quantum key distribution can be done
1.Without using Entanglement example:bb84 protocol
In this protocol we do not use entanglement but we use the uncertainty principle or the no cloning theorem for non orthogonal states to protect the information.
2.With Entanglement example:EPR protocol
The critical elements to be developed in QKD:
- Quantum source
- QKD simulations
- QKD protocol
- Sifting
- Privacy amplification
- Error correction
- Secure key.
Similarly there is the b92 protocol which is also a prepare and measure protocol so b92 is essentially a modified version of bb84 the only difference here is that instead of using four bases we use two bases.

Dear ma'am! Your efforts are strengthening India against china which is well ahead from everyone.. Huge responsibilities on you . Keep going
Beautifully explained

i am here just to collect info for my college project
dont mind me
