Day 17 of the #Quantum30 of the Quantum Computing India completed! We define qubits more rigorously and see the probability - amplitude relation in action. Link to the summary attached below:

Ordinary computers store information as binary digits, or bits, which can be either zeros or ones. Quantum computers use qubits, or quantum bits, which are much richer objects. Their values can be a complex mixture of zero and one because they rely on this behavior of atoms and smaller particles. Qubits can also coordinate their actions with other qubits instantaneously, no matter how far apart they are—a phenomenon that Albert Einstein called “spooky action at a distance.” 

#cohort06 #quantum30 today the lessons were mostly focused about quantum annealers. What are quantum annealers and how do they function, how qubits are used to form a quantum annealer. It also teaches us about universal gate-based quantum computer and how they differ from the quantum annealer. disscussion about quantum gates like Hadamard gate & CNOT gate ( 1 &2 qubits respectively), fredkin gate & tofolli gate were very informative and would love to know more about them during further study. factors that determines the performance of a quantum computer ( eg. divincenzo criteria, quantum volume) were also important topics to focus deeply.

#QuestionsWorthAsking: Is the effort to create "error-corrected" qubits in quantum processing really trying to fit a square peg into a round hole? Quantum spin by definition is multi-value. Forcing one answer to be the correct one is an extension of bias/linear thinking. Perhaps, we should embrace the qubits for what they are. To quote Denzel Washington in The Equalizer: "Man gotta be the man, fish gotta be the fish."

At the turn of the #2000s, David P. #DiVincenzo, elaborated some principles which has guided researchers trying to build #quantumcomputers over the past two decades. It is a list of #criteria that every quantum computer which — as highlighted in one of our previous posts was first proposed by the physicist Richard #Feynman in 1982 as a means to efficiently simulate quantum systems - should satisfy. DiVincenzo’s criteria are #seven conditions an experimental setup must satisfy to successfully implement quantum algorithms. The first five regard quantum computation itself. Two additional conditions regard implementing quantum #communication, such as that used in #QuantumKeyDistribution: • the ability to interconvert stationary and flying qubits • the ability to faithfully transmit flying qubits between specified locations.

Day 13 of #100DaysOfQuantum Hello Everyone! 👋 The second video in the Quantum with Q# playlist, "Single Qubit Gates using Q#," is now out, and you can watch it using the link below. Some of the concepts we explore in the video are: 1) How classical gates are used to implement operations in classical computers. 2) What makes quantum gates different from classical gates. 3) The matrix representation of quantum gates. 4) A mathematical example of the working of the Pauli X quantum gate. 5) Hands-on implementation of the Pauli X gate, Hadamard gate, Pauli Z gate, and the rotation Rx gate (with Bloch Sphere visualization). #100daysOfCode #quantum #quantumcomputing #qubit #microsoft #qsharp #katas #vscode #youtube #tutorial Satwik Sukhavasi Safal Antony Aishwarya Ann Joseph Ashwin Arumugam ARUN S KURIAN Immanuel Joshua Aleena Mary Benny Sabari Thiru

[...]"Ongoing research indicates progress in developing scalable error correction methods tailored to the unique nature of quantum systems, rather than focusing on increasing the number of qubits for a Quantum Computer system – this will ensure that the calculations will be more accurate".
