To many researchers, the universe behaves like a gigantic quantum computer that is busy processing all the information it contains.
The roads were dark. The sky was as black as if it had swallowed the sun. Raj was running away from someone. He didn’t see his face but after hearing the loud footsteps, he understood that from one he is running away was a demon. After a few seconds, he realized that the roads were narrowing and he couldn’t even breathe. He started running fast. Suddenly, a small pebble came under his feet and he fell and saw the demon was about to tread on him. He cried out for help. ‘What happened then?’ asked Ishan. Ishan was a very good friend of Raj. ‘I don’t know. I woke up sweating.’ said Raj. ‘Dreams are related to what you think throughout the day. And after the sudden death of your father, you are going through hard times mentally. These scary dreams are just the result of it.’ said Ishan. ‘SHUT UP! My father hasn’t died. He just disappeared doing his experiment.’ shouted Raj. ‘I still remember the night before the experiment. He was explaining to me, how he understood the bunch of maps what my grandfather had given him at the time of his death by saying the last words Quantum Maps and he showed three fingers.’ said Raj. ‘My father told me that the maps are called Quantum Maps because they are related to a quantum phenomenon, called Entanglement and it will lead to a treasure. I stopped him that night and said, “I don’t believe in this nonsense story”. I should have listened to him. I can’t forgive myself.’ cried Raj.
‘Do you have your father’s notebook. It can lead to your father.’ said Ishan. ‘Yes, I tried to understand it but it went over my head. It is full of Quantum Physics.’ replied Raj. ‘Don’t worry, I know Quantum Physics very well.’ said Ishan. Raj gave the diary of his father to Ishan.
‘Here it is written that, there is a place in your house that is a way to another world. That world is dual of our world. The Map will show the path to it.’ said Ishan. ‘Rubbish, how can there be another world?’ said Raj. ‘In Quantum Mechanics, a system is described by a state vector and there exists a dual space where the state vector is just the complex conjugate followed by the transpose of the original state vector. In Many-Worlds Interpretation of Quantum Mechanics also, there exist many worlds like our own.’ said Ishan. ‘It’s a lot to think about.’ said Raj. ‘What’s written more?’
‘The treasure in the dual world is in a box which takes the shape of either zero or one. There are two buttons on it, one of zero and other of one. If you press the correct button, you will get the treasure otherwise the monsters will follow you. But even after pressing the correct button you have to leave in two minutes, otherwise the treasure will go back into the box.’ said Ishan. ‘My father must have been caught by the monsters.’ said Raj. Ishan stopped him and said ‘No, it can’t happen. The way to press the correct button is also written in the diary. The treasure behaves like the sigma X operator, which flips the bit. That means the correct button will be the opposite of the shape of the treasure box. So, don’t worry. There is something else that has happened.’ said Ishan. Raj breathed the sign of relief and asked “But there is one more thing that is scratching my brain”. ‘What is the meaning of three, what my grandfather showed’. ‘Maybe the map can help us’ said Ishan.
Both of them started analyzing the Maps. ‘As your father had pointed out, the maps are related to Quantum Entanglement and Entanglement is about the correlations of the states. It means that every map is related to one another.’ said Ishan. ‘Entanglement is a combined property, there is no place of individuality. So, we have to see all the maps at one shot, only then it will make sense to us.’
Both of them placed all the maps together and it looked like a symbol. Suddenly Raj shouted ‘I have seen it, it’s in my basement.’ Both of them rushed to the basement. After a few seconds, Raj found the symbol and pressed it. And suddenly everything around them changed. They found themselves in a dark forest, which was divided by a road. They were now in the dual world. The wind blew whenever Raj thought about his father. The wind tried to give a hint. Suddenly they found the treasure box in the shape of one and without waiting they pressed zero button. After pressing it, the treasure came out of the box. Ishan took it. Instantly, a demon started running towards them. Both of them started running away from him. ‘Why is the demon following us?’ asked Ishan. ‘It was not in the diary.’ ‘You can’t have a perfect plan. Deal with it. RUN!’ said Raj. After a few seconds, Ishan noticed that the roads were narrowing and he was unable to catch his breath. Ishan said while running ‘all of this is happening like your dream’. Instantaneously, Raj stopped to see the demon and got stunned. The demon was his father. He cried with a loud voice PAPAA! ‘Let’s go home. I have spent long nights being awoken and crying.’ The demon lifted Raj with his big hands to eat. Raj again cried with a louder voice. ‘How long do you make me wait? The hope of your sight had become eternal. My heart is craving for your love.’ The demon lifted Ishan with his other hand and whispered in their ears. ‘I love you kids. Let’s go home.’ All three of them started running to the exit. At the exit, it was written that the gate will open only if the number of people is three. ‘Maybe that’s what your grandfather had been pointing to for three’, said Ishan.
