54 Creating Nanowires (Majorana fermions qubits)



After being handed the key to the lab he turned to his security team and told “I probably won’t be leaving the lab for about a month, arrange your shifts accordingly also don’t forget to bring me my meals, use this for your needs while I’m in the lab” Aron said while handing them a debit card for their use.

After he finished giving his instruction he returned to the lab shortly after wearing clothes needed for the clean room he was about to enter and begin his work.

After closing the door behind him he removed his phone from the pocket and connected it to one of the computers in the room using a USB cable.

“Nova it’s time to work” Aron said as a signal for Nova to connect herself to the lab’s computers so that she can be his assistant.

[I’m done Sir] Nova replied shortly after taking over all of the computers and machines in the lab.

“Okay, let’s create a bigger brain for you,”

“Now we start with the creation of Majorana fermion qubits and for that we need to create Majorana fermion”

Creating Majorana fermions is a key step in developing qubits for the quantum chip he wanted to create.

Majorana fermions are particles that are their own antiparticle, and they have unique properties that make them ideal for use in qubits.

Unlike ordinary particles, Majorana fermions obey non-Abelian statistics.

This means that when two Majorana fermions are exchanged, the result depends on the order in which the exchange takes place. This property is important for performing topological quantum computations.

To create Majorana fermions, He needed to fabricate a nanowire made of a semiconductor material indium arsenide.

He started this process by trying to grow the nanowire using a technique called molecular beam epitaxy (MBE).

After putting the indium arsenide in the machine and closing the door Aron said ” Create a vacuum chamber and heat the semiconductor material then allow it to condense on a substrate and form a thin film.”

[Yes sir] Nova replied and started the machine by starting to remove the air in it to create a vacuum and begin the next process.

Aron, who was watching the process, added “Make sure you keep an eye on the machine’s parameters for us to find optimal settings we can use.”

[Yes sir, but it might be difficult to find the optimal setting of the machine by the first try.] Nova informed Aron, so that he doesn’t get his hopes up.

“I know, don’t worry about failing.” Nova said as he sat down in front of another computer and said “Send a copy of my IDE(programs used for writing, testing, and debugging code) to this computer”

Nova did as asked and sent a copy of Aron IDE to the computer he sat on from her servers.

[Are you developing something else while you wait for the process to be done?] Nova asked.

“Yeah, I’m writing the firmware for the quantum chip” Aron answered Nova’s question then started typing like a machine gun.

Lines and lines of code in prometheus++ where appearing like they were being written by machine, no mistakes were made at all since he started typing the instruction.

He didn’t have to stop and think for anything because everything was assimilated in his head when he bought the knowledge from the system shop.

Despite prometheus++ being able to write many instruction in just short lines by the time an hour had passed, Aron was more than 97 thousand lines of code in and he wasn’t even a quarter of a quarter of the way done.

As for Nova she wasn’t even halfway done with her first trial of making Majorana fermions.

7 hours later.

[Sir it’s done] Nova said to Aron through the lab’s speakers.

Aron, who was in the zone, finally stopped after typing in a few more lines when Nova called him.

“Okay now let’s take a look at the results.” Aron said while heading to the MBE machine.

After removing the Said nanowire created by Nova he headed to the electronic microscope and inserted it in.

“You can begin,” He said to Nova after he finished inserting the nanowire in the microscope.

Nova started taking images of the nanowire and showing the results on the screen in front of Aron.

Aron skimmed through the images and was slightly disappointed after finding out that the nanowire was very defective.

Although he expected a failure on his first try he still had a slim hope to succeed in his first try.

“Show me the machine’s parameter during the time which the nanowire came out as perfect” Aron said wanting to know what changed to cause the defects to appear on the nanowires.

Nova did as asked and showed Aron what he asked for. After looking through the parameters he asked “What happened at this timeline”

He asked that because the parameters went wild during a period where most of the defects seemed to appear.

[The Machine seemed to have trouble keeping constant power control over a long period of time]

“Take over its power control and all other things that seemed to have caused the defects” Aron said after learning what caused the defects.

[Yes Sir.] Nova immediately took over control of the entire machine and not just what Aron asked him to take over. She wanted to avoid any more chances for other problems to arise.

Aron put the indium arsenide in the machine for the second time and closed the machine’s door.

“Start the process” He said and waited for the process to begin, then he returned to the computer to continue with the writing of the firmware.

Two hours later.

[Sir you need to eat] Nova reminded Aron that he hasn’t eaten for more than 9 hours.

“Thanks” Aron said as he left the lab to eat outside as he couldn’t bring the food in due to the lab being a clean room and nothing even dust is allowed to avoid contamination of the machine.

5 hours later.

[Sir the process is done] Nova called to the Aron who returned to his typing routine after eating his food outside with the guards.

Aron stood up from his chair once again and repeated the process of removing the nanowires and placing them in the electronic microscopes.

“Woooh” Aron couldn’t help but jump in joy when he checked the results and found out that they were perfect and defect-free as he needed them to be.

[Congratulations Sir] Nova congratulated Aron in succeeding to make his first perfect nanowires.

“You did most of the hard work, take some credits too”

[Thankyou Sir.]

After making sure the nanowires were as he needed them to be, he took them and brought them to another machine that he started using to bring the nanowires into contact with a superconductor.

The machine did this by depositing a thin layer of superconducting material niobium on top of the nanowires.

When the wires and the superconducting material come in contact, the superconducting material induces superconductivity in nanowire which results in the creation of Majorana fermions qubits at the end of the nanowires.

After that he put the qubits in a freezer and he returned to continue with the creation of another batch of nanowires, as the ones he made weren’t nearly enough to meet his demands.
