Some historical events in Quantum and Classical Computing

Once upon a time Jack and Jill went up the hill, to fetch a pail of water. Jack fell and broke his crown and Jill came tumbling after. Both went mad because Jill was lost in history and Jack became a dunce.

• Jill: Hey Jack! I can see the history.

• Jack: What history? Ah, history I don't like. But which history?

• Jill: History of computers. The one which we use in our school on which we can play computer games. But I am also able to see something different.

• Jack: Ohh! Computers. Please don't see something different in them. Whenever you imagine something different it creates havoc for both of us. I love to play Roadrash, GTA and my favorite one Counter-Strike. I don't want any changes in them. But why are you going into history? Come in the present.

• Jill: SHUT UP JACK! Let me tell you what is there in my imagination.

• Jack: As always I have to keep quiet when you speak! Okay, tell me.

• Jill: I am in 1965 when Olliveti unveiled 'The Programma 101' to the masses at World Fair.

• Jack: I think so we have to go to the mental hospital where people who can see histories are treated. Let's go there. I have to admit you. What is this 'Programma 101'?

• Jill: Patience Jack! At the event, Olliveti entered a card with the program in this computer and ran it. Within a few seconds, it calculated the orbit of the satellite. At that time it was an eye-opener.

• Jack: I am not able to get my bottle opener. By the way, who is this Olliveti?

• Jill: It was an Italian company.

• Jack: Wow! I want to work in a company. But let's first complete our primary school. Come on Jill we have to reach home and do some math homework. Write numbers from 1 to 25 in words.

• Jill: No Jack! I have gone in the past. Until I don't come back in the present neither I will go home nor you can go. Let's enjoy history step by step.

• Jack: Jill if I do not complete the homework teacher will beat me with a ruler. It hits hard.

• Jill: Don't worry nothing will happen. Don't waste your time. Just listen. Next is the year 1981. IBM's personal computer named IBM 5150 was introduced in August 1981.

• Jack: What is IBM?

• Jill: It is International Business Machine Corporation and it is an American Multinational Technology Corporation.

• Jack: I think so Jill you are not in the past. You have gone too ahead in the future. Everything is just going as a bouncer. Let's play Hide and Seek. Leave the history.

• Jill: Keep Quiet and listen. In 1981 IBM introduced its Personal Computer and in the same year, Richard Feynmann proposed the idea of quantum computing.

• Jack: What? Which computing? qua, quan, What is the spelling?

• Jill: It's Q, U, A, N, T, U, M

• Jack: Ohh! I recently saw one movie with the same spelling but there were 4 more letters after it A, N, I, A.

• Jill: Stop watching movies and complete your homework. So you won't get any beatings from the teacher.

• Jack: If you are done with your history I can go home and complete my homework.

• Jill: No Jack! It's just 1981, a start. Feynmann and Beniof proposed simulating quantum mechanics with a quantum mechanical system. Next, in 1986, Feynmann introduced a notation for Quantum Gates. Like a dot and circle notation for the CNOT gate.

• Jack: What is this Quantum Mechanics, Quantum Gates? Which notation? What is CNOT? You have gone mad.

• Jill: No I have not gone mad! I have gone in history. Don't worry these terms are not for you Jack. It's for the people who are reading this blog and they know some basic ideas on Quantum Technology. In 1992, Deutsch and Jozsa discovered a quantum algorithm exponentially faster than classical algorithms.

• Jack: Ohh Wow! It's a DJ algorithm. Deutsch and Jozsa. Let's party.

• Jill: Stop uttering lame jokes, Jack! I forgot one thing in between. In 1990 first internet browser was developed by Tim Berners Lee.

• Jack: What is a browser?

• Jill: STUPID! It's the place where you play your online games. Where you visit different websites like Google, Facebook etc. You don't know anything!

• Jack: Don't tell like that! I at least know counting from 1 to 100 and also A-Z. Now I will keep quiet and Jill you complete your history. It's getting late.

• Jill: Okay! Before you become completely stupid. Let me finish. In 1994 the first physical quantum gate was built using 'cold trapped ions'. Shor's algorithm was discovered in the same year. This algorithm changed cybersecurity as we know it today. It was proven that quantum computers could solve practical problems faster than classical problems by 1994.

• Jack: Ohh! So now I can kill enemies much faster in my Counter-Strike Game.

• Jill: Idiot Quantum Computing is not developed yet to run your Counter-Strike Game. In 1995, Schumacher coined the term qubit for a quantum bit. In 1998 first experimental demonstration of quantum algorithms on a working 2-qubit quantum computer was done. In 1999 Wifi Routers became available. In 2007, the first iPhone was launched.

• Jack: Ohh iPhone. I want one iPhone. I need an iPhone.

• Jill: First learn to tie the lace of your track pant then you will get your iPhone. Fast forwarding in 2017 Cloud Based Quantum Computing was introduced. In 2019 first demonstration of a quantum computer outperforming a classical computer. In 2023, IBM unveiled its 433 qubit Osprey Processor. Yes! I have arrived in the present. Come on let's go home, Jack!

• Jack: Wait! When were Photonic Quantum Computer and Diamond NV center Quantum Computer introduced?

• Jill: But I never told these terms in my talk.

• Jack: Ya but I think so now I have gone into the past now.

• Jill: JACKKK! Come on. We don't have time. Let's go home. Even the readers are bored with us.

Conclusion:

From Jack and Jill's talk, we came to know that Quantum Computing is not a recent technology but it took birth way earlier in the year 1981.
