Post Graduate Department of Physics of Sri Guru Gobind Singh College organised a Webinar on the topic ‘Quantum Computers’ on 13th May, 2021. Dr. Bindiya Arora, Assistant Professor, Department of Physics, Guru Nanak Dev University, Amritsar was the speaker of the webinar. Vice Principal Professor Dr. Ginny Kang was the chief guest of the webinar. Professor Kang inaugurated the webinar and welcomed Dr. Arora to start the interactive session.
With a brief introduction to quantum mechanics Dr. Arora introduced the idea of macro and micro world to the students. During the session she talked about the probabilistic nature of quantum system in comparison to the classical system. The speaker discussed about the ‘quantum entanglement’, which is an important phenomena of quantum system and used in teleportation. The basic idea of quantum computers was introduced to the students in very lucid and interesting way by the speaker.
The speaker gave the idea of ‘Qubits’ which are the building blocks of quantum computers. She discussed why the quantum computers are more powerful and faster in comparison to the classical computers. The former one uses qubits, which have larger possibility to store information than to the ‘bits’, which are the building blocks of classical computers. She also discussed that the quantum parallelism is responsible for the faster speed of quantum computers. The speaker discussed that to form a quantum computer a quantum system needs to follow the five steps, such as, (qubits, initialization, universal set of quantum gates, long relevant decoherence time and ability to efficiently read out the result).
Dr. Arora also talked about different experimental schemes which can form the quantum computers, like, liquid NMR, trapped ions, solid state scheme etc. At the end she discussed about the several challenge of build quantum computers, amidst which the perturbation by the environment is the most significant as mentioned by her. She also encouraged students through her talk discussing about numerous career options in quantum computers both in industries as well as academia.
- Arora also responded to various queries by the students. The webinar was attended by around 140 participants. Professor Kulwinder Singh, Head of Physics Department thanked the speaker for her interesting talk and extended vote of thanks to conclude the session.
