What is Quantum Computing in simple words?
Quantum computing is a new type of computation that uses the principles of quantum mechanics, like
superposition and entanglement, to solve complex problems much faster than regular computers. Unlike
classical computers that use bits ($0$s or $1$s), quantum computers use qubits which can be both (0) and (1) at the same time, allowing them to explore many possibilities simultaneously.
How it works:
*Qubits: The basic unit of quantum information. While a classical bit is either (0) or (1), a qubit can be (0), (1), or a combination of both at the same time (superposition).
*Superposition: A qubit can exist in multiple states at once. This allows a quantum computer to perform many calculations in parallel, a capability classical computers lack.
*Entanglement: A phenomenon where two or more qubits become linked, so that they share the same
fate no matter how far apart they are. Measuring the state of one entangled qubit instantly influences the state of the other.
*Quantum Interference: The behaviour of qubits can be manipulated
so that incorrect answers cancel each other out, while correct answers reinforce each other, leading to the desired result.
Potential applications:
*Developing new medicines and materials by simulating molecular behaviour.
*Improving machine learning algorithms.
*Solving complex optimization problems in fields like finance and logistics. Breaking current encryption methods, and also creating new, more secure ones.

What does Elon Musk say about quantum computing?
Musk said the technology now “appears to be becoming relevant.” Earlier in the day, Google unveiled that
its new Willow quantum chip had achieved a verifiable quantum advantage, running the Quantum Echoes
algorithm 13,000 times faster than one of the world’s most powerful classical supercomputers.
What did Bill Gates say about quantum computing?
Gates said, “There is the possibility that [Huang] could be wrong.” He added, “There is the possibility in the next three to five years that one of these techniques would get enough true logical qubits [the basic unit of information in quantum computing] to solve some very tough problems.”
Which IIT has quantum computing in India ?
Several IITs, including IIT Madras, IIT Delhi, and IIT Bombay, are actively involved in quantum computing
research and education. IIT Madras has established the Centre for Quantum Information, Communication and Computing (CQuICC) and is part of the IBM Quantum Network. Other IITs like IIT Mandi are developing indigenous quantum computers, and others like IIT Jodhpur and IIT Roorkee are establishing programs and collaborations in the field.
Who has the best quantum computer?
There is no single “best” quantum computer, as different companies lead in different areas of development, such as IBM for cloud access and modular systems, Google for achieving “quantum supremacy” with its Sycamore processor, and IonQ for its focus on trapped-ion technology and high fidelity. Other major players include Microsoft, Amazon, and Intel, each with unique approaches to hardware and software development.
Key players and their strengths >>
*IBM: Considered a leader in quantum computing, IBM provides cloud-based access and is developing modular, utility-scale systems like Quantum System Two to build larger quantum supercomputers.
*Google: The Google Quantum AI team achieved “quantum supremacy” with its Sycamore processor and is continuing to develop its hardware, with the Willow chip showing promise for error correction.
*IonQ: This company is focused on trapped-ion technology, which is known for high performance and scalability. For 2025, IonQ is targeting extremely high fidelity rates for its quantum gates.
*Microsoft: Microsoft’s Azure Quantum platform provides a comprehensive set of tools and resources, and the company is actively working on developing its own scalable, fault-tolerant quantum computer.
*Amazon: Amazon Web Services has its Amazon Braket service, which provides access to various quantum hardware.
*Intel: Intel is developing full-stack commercial quantum systems.
*D-Wave: This company specializes in quantum annealing systems, which use a different approach to quantum computation compared to gate-based systems.
How much RAM is in a quantum computer?
Whereas ordinary memory stores information as binary states (represented by “1”s and “0”s), quantum memory
stores a quantum state for later retrieval. These states hold useful computational information known as
qubits. How much RAM does a quantum computer
have? It had 500 KB of RAM and 233 megabytes of hard disk space.
What is the biggest problem with quantum computing?
Decoherence. Compared to classical computers, quantum computers are extremely susceptible to noise, as the quantum state of qubits is very fragile and any perturbation, such as a slight vibration or a change
in temperature, can affect them uncontrollably, causing the stored information to be lost.
Do human brains use quantum computing?
As a result, we can deduce that those brain functions must be quantum. “Because these brain functions were
also correlated to short-term memory performance and conscious awareness, it is likely that those quantum
processes are an important part of our cognitive and conscious brain functions.
