The Future of Computing

Efficient computing systems will be the backbone of businesses in the future. Our innovation on quantum technologies relies on high-performance and energy-efficient computing systems to meet the growing demands of multi-compute converging use cases.

The Evolution

Quantum physics and its principles have existed since 1920, but the change that has happened now in where hardware is making quantum computing practical.

Two significant changes have pushed this boundary:

Quantum Annealing

Quantum Annealing is the process where we use the universal law of how the energy of any system tends to take the minimal path. The energy of any object in the world is referred to by a term called the ‘Hamiltonian’. Although a Hamiltonian is a big term, in simple terms, it means the energy of a physical system. It can also be regarded as a combination of potential energy and kinetic energy.

A ball on a table has a higher Hamiltonian (potential energy) than one on the ground. Now, consider if I can code a mathematical equation in terms of energy and give it to a quantum computer, the universe itself would try and find the lowest possible energy state, which turns out to be the global minimum of energy. In simplistic terms, optimization problems can be solved in this manner, and they are. Examples include positioning satellites in orbit for portfolio optimization. In a quantum annealer, we have as many as 1000 qubits working at a hardware level. There are applications of quantum annealers in the practical domain, and companies like D-wave are pushing the envelope there.

Push towards Universal Quantum Computer

The other push is the creation of a universal computer that works on the same principles as our classical (current) computers. This includes formulating gates like ‘AND’ and' NAND’ using qubits (quantum bits).

Over the past few years, the error in qubits has been reduced, giving more viable breakthroughs for quantum computing in the future. There are a few organizations that are on this path. IBM is a prominent one in this regard. The IBM quantum computer uses superconducting transmon qubits, which work to ensure gate computing comes to the fore. Today, the IBM quantum computer has around 400 K+ users, about 3.5 B+ daily transactions, and 170+ members of their quantum network, of which Tech Mahindra is also a part. IBM has an Eagle quantum computer accessible via their cloud, providing 127 qubits, and there is a plan to go further with as many as 1000 qubits. This would significantly transform the computing landscape in 3-5 years.

Tech Mahindra’s Approach to Quantum Computing

Makers Lab has been incubating this technology since the inception and we have been focusing on the areas of:

  • Quantum Security
  • Quantum Machine Learning

Key Focus Areas

Customer Focus
  • The approach for quantum computing has been to enable our clients to use quantum computing and quantum-triggered algorithms to solve real-life problems.
  • To enable this, we have mapped different domains to use cases, and these use cases are used in major quantum algorithms.
  • We have engaged with different clients to help them understand how quantum computing works.
  • Further, we have discussed these use cases with them, enabling them to view practical examples of the usage of quantum computing.
  • We have been on-boarded with CDAC for joint work in areas like quantum security, sensing, and networks.
Building Capability
  • A course in quantum computing was co-designed with Mahindra University, and the first batch of students and professionals – Tech Mahindra associates have also completed this course. The objective is to enable the creation of a talent pool to work on quantum computing.
  • Engage actively with the ecosystem to assess the products being created in the quantum computing space and put agreements in place to enable training for our teams on these platforms.
Building Ecosystem
  • We have forged alliances with Infrastructure providers (IBM Quantum, AWS, IQM, and others), start-ups (QNu Labs, Cogniframe, Multiverse Computing, BosonQPsi), governments (CDAC-MEITY, IIT Madras), and academia (Mahindra University, Aalto University), to enable an ecosystem that will work together to progress quantum use cases.
  • With the alliance partners, we intend to create use cases to enable our clients' quantum computing use cases.
