Quantum Computation and Quantum Information

By Prof. Chiranjib Mitra   |   IISER Kolkata
Learners enrolled: 895   |  Exam registration: 20
ABOUT THE COURSE:

This course is based on the course Quantum Information Processing that I have been giving at IISER Kolkata for more than 6 years, the link of the course is: ://www.iiserkol.ac.in/teaching-plan/course/2022/Spring/PH4207/
This course is meant for 4th year B Tech or BS students who have the prerequisites of Intermediate Quantum Mechanics, Mathematical Methods and Statistical Mechanics. Here the course is somewhat formal and not very application oriented. Some background in linear algebra is desirable. We assume the students to be familiar with Hilbert Space structure and inner product and the bra ket notation. However, rotation operators etc will be introduced in the course for quantum gates. Some knowledge of Tensors would be helpful, however, if the student does not know, then it would be introduced.

INTENDED AUDIENCE: Masters or advanced undergraduate students

PREREQUISITES: Basic Quantum Mechanics, Basic Statistical Mechanics, Basic Mathematical Physics, Condensed Matter Physics, Basic Optics

INDUSTRY SUPPORT:
  1. Cybersecurity & Cryptography: The course covers classical and quantum cryptography, including RSA encryption, which is fundamental to securing data and communications.
  2. Finance & Data Science: Topics like Shor's algorithm for factorization and Grover's search algorithm are highly relevant for a future in finance and data analysis, as they offer the potential for faster data processing and complex problem-solving.
  3. Technology & Computing: The course delves into the physical realization of quantum computers, including NMR and superconducting qubits. This is crucial for hardware development in the computer industry.
  4. Telecommunications: The study of quantum protocols, such as teleportation and quantum dense coding, is directly applicable to developing new methods for secure and efficient communication.
  5. Aerospace & Defense: The principles of quantum computation and information theory have potential applications in advanced navigation, satellite communication, and secure systems for the aerospace and defense sectors.

Instructor bio

Prof. Chiranjib Mitra

IISER Kolkata
Prof Chiranjib Mitra is an experimental physicist who works in experimental quantum information processing (QIP). He works on spin qubits, mostly in low dimensional spin systems. His primary research focussed on characterising entanglement through experimental entanglement witness operators. He also works on QIP in nitrogen vacancy centers in diamond. He has been teaching a fourth year BS-MS advanced course on Quantum Information and Quantum Computation at IISER Kolkata for more than 5 years. He has also been involved with formulating the course on QIP at IISER Kolkata since its inception.
He did his PhD from TIFR, Mumbai in 2001 and has done a post-doc in Germany for one and half years, then in Cambridge University for 2 years and subsequently was in University College London for three and a half years. He joined IISER Kolkata as an Assistant Professor in December 2007 and became an Associate Professor in December 2012. Since October 2018, he has been a Professor in the Dept of Physical Sciences at IISER Kolkata.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: April 25, 2026 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

Please note that assignments encompass all types (including quizzes, programming tasks, and essay submissions) available in the specific week.

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.
