Present Status Of Quantum Based Superfast Computers

This article is a review of the present status of quantum computers, which can solve certain problems much faster than a classical computer. Their future is now much more exciting and awaited

A computer is a device that takes an input, carries out a sequence of instructions, and produces an output. In a digital computer, these inputs, instructions and outputs are all sequences of 1s and 0s—individually called bits. A quantum computer is one that harnesses phenomena from quantum physics, the study of the behaviour of subatomic particles.

A quantum computer does the same thing as a classical computer, but it uses quantum bits or qubits. While a bit takes only one of the two values—1 or 0, a qubit uses the complex mathematics of quantum mechanics, providing a richer set of possibilities. As binary digits or bits are the basic units of information in classical computing, quantum bits or

Programming a Quantum Computer – Towards Data Science

Qubit States in QISKit

First, you’ll need to download a free distribution of Anaconda so that you can use Jupyter Lab. Once you’ve downloaded Anaconda, open the Anaconda navigator and open an instance of Jupyter Lab. If you’d like to download the notebook from Github, you can find it here. If you’d like to see the interactive version on Binder, you can find it here. To install QISKit, you can just use pip in Jupyter notebook or Jupyter Lab.

Next, you’ll need to import qiskit and matplotlib.

Now, if you want to plot the “Spin-Up” state on the Bloch Sphere, you can type the following command.

We can plot the “Spin-Down” state of the qubit with the following command.

In general, qubit states are no longer restricted to simple 0 or 1 like a classical binary bit of information. Qubits can be in infinitely many states. Each state is represented

Delta partners with IBM to explore quantum computing – an airline industry first


“Partnering with innovative companies like IBM is one way Delta stays on the leading edge of tech to better serve our customers and our people, while drawing the blueprints for application across our industry,” said Rahul Samant, Delta’s CIO. “We’ve done this most recently with biometrics in our international terminals and we’re excited to explore how quantum computing can be applied to address challenges across the day of travel.”
