As part of our #PeerLearning series, we had Nishmitha present part two of her book review.

In this book review, Nishmita covers the last five chapters of the book Dancing with Qubits. She summarises the following chapters:

-One Qubit

-Two Qubits, Three

-Wiring up a circuit

-From Circuits to algorithms

-Getting physical

What? Shor’s Algorithm watch party?

What does that mean ? We’ve been learning about Quantum Cryptography the entire month of August and now we are on to CoCreation.

What is CoCreation? Its a process through which a community learns. Hackathon/HackSeries sounds very brittle as a hack is never a sustainable solution.

Who can attend? Anyone interested in contributing to #BreakRSA project. We start with understanding the Shor’s algorithm then do a comparative study of its implementations across platforms then find ways to optimise the parameters under our control.

When? 10–11 PM IST on Zoom — 8 & 9 September —…


As part of the #PeerLearning Series, Quantum Computing India had a session on Continuous variable QKD Protocols by Vaibhav Bajpai. He is an Aerospace Engineer graduate from IIT Kharagpur who turned into a software developer.

- Example — Alice & Bob

- Coherent-State Protocol (homodyne detection)

- No-Switching Protocol (homodyne detection)

- Squeezed State Protocol

- Fully-Gaussian protocols and entanglement-based representation

- Postselection

- Discrete modulation of Gaussian states

  • Two-way quantum communication
