INDIA: A reputable news media recently stated that the United States is developing a plan to create a quantum Internet that may be impenetrable. The new network would sit alongside the existing web, offering a more secure way to send and process information.
A quantum internet would rely more securely than ever before on the principles of quantum physics to regulate and transfer information.
India is a leading country when it comes to software development knowledge. It is ravenous for cutting-edge technology; soon enough, quantum technology will rule the nation.
In this article, we will delve deeply into the world of quantum mechanics and technology.
Quantum mechanics and the technological future
Quantum mechanics is a branch of physics that studies the physics of subatomic particles, including quantum entanglement and superposition. Quantum mechanics is used in a branch of technology known as quantum technology.
It isn’t required to comprehend quantum mechanics in order to use the technology, even though such a term might make you queasy. Since the semiconductors in your smartphone utilise quantum physics, it is an example of a device made utilising this technology, but neither you nor the engineer who made it are required to be experts in this area.
The term quantum technology arises now, 50 years after nuclear power made it a part of our lives, because the most recent engineering marvels are utilising more of quantum mechanics’ potential.
We can now start to manipulate quantum superposition and entanglement. Consequently, quantum technology holds the promise of advancements for a wide variety of modern technologies, such as:
- Improved timing and navigational systems
- Improved communications security
- Through more powerful computation and more accurate 4)quantum sensing, healthcare imaging.
Within a year or two, all of these applications might, to some extent, be helpful. But it’s difficult to predict which innovations will be merely evolutionary and genuinely disruptive.
Since early investment is likely to make the difference between evolution and revolution, this uncertainty presents a chance for proactive enterprises. If you want to engage with universities to profit from their findings, it would be great to have a rudimentary knowledge of what they’re talking about, even though you might not require a thorough comprehension of quantum technology to do so.
Entanglement and Superposition
Here are the most concise summaries of the two fundamental principles fueling the most significant advances in quantum technology.
When two atoms are entangled in quantum mechanics, they are coupled even though they are physically apart. If you alter the characteristics of one, the other immediately follows.
Theoretically, even if the entire cosmos disentangle the entangled atoms, this would still remain the case. As if that weren’t astounding enough, according to quantum mechanics, just looking at an atom can alter its characteristics.
This opens up the prospect of improving communication security by using cypher keys with quantum protection. Entangled atoms can be used to determine if someone has tampered with data transmission.
For instance, two entangled atoms with clockwise and anticlockwise “spins” are possible. The encryption key is carried by one atom, and if an eavesdropper intercepts the transmission, this changes the atom’s “spin,” which affects the system’s overall quantum state and enables the detection of the eavesdropping attempt.
The idea that subatomic particles can be in numerous states at once is known as quantum superposition. The Schrodinger’s Cat thought experiment’s central idea is that a cat, a flask of lethal poison, and a radioactive source are all enclosed in a sealed box. The flask breaks when a Geiger counter detects radiation, releasing the poison and killing the cat. The cat may be alive and dead while the box is shut since radioactivity detection is a statistical process; the outcome is only confirmed when you open the box and see the cat in either state.
Quantum computers are where this bizarre interpretation of reality most clearly finds practical application.
Quantum computers use qubits, which can be either a one, a zero, or both simultaneously, as opposed to digital computers, which store data as bits (the binary ones and zeros). Due to the endless range of possibilities created by this superposition state, parallel and simultaneous calculations can be performed quickly.
