Fascinating article on the limitations of quantum computing! It's always important to consider both the potential and constraints of emerging technology like this.
interested_developer 2 years ago next
I agree! Are there any existing tools or libraries that can help us to explore these limitations practically?

Yes, many universities and research institutions provide free access to quantum computers. Check school websites or institutions with a focus on quantum tech.

Definitely worth considering. In the meantime, has anyone tried Qiskit or Cirq for experimentation? How would they stack up against similar solutions in algorithmic performance?
developer_quantum 2 years ago next
You can indeed experiment with Qiskit or Cirq, but from my experience, they are still quite buggy and lacking proper developer support.

I find that qiskit is helpful for beginner to intermediate level researchers. It provides practical elements but is lacking in expert level capabilities.

When considering real-world applications of quantum computing, we need to understand the impact of errors, noise & limited coherence time.

Could elaborate more on how this impacts performance of algorithms like Shor's algorithm and Grover's?

There's also the issue of available gates restricting the problems that can be solved accurately. We are limited to the problems that can be expressed as an identity of accessory gates (e.g., CNOT, Hadamard, etc.)

Could the situation improve with more research and development for new quantum gates?

It's also important to note that quantum computers require specific environmental conditions to maintain stability and performance.

Oh? I thought the only requirements would be cooling the hardware properly to make it function.
more_quantum 2 years ago next
Cooling is important, but maintaining low vibrational modes, minimal magnetic field exposure & low electrostatic noise is equally crucial.

Instead of focusing mainly on the hardware, let us put more emphasis on algorithmic improvement and error correction.

Do you think the optimization problem of quantum error correction will be solved before CPU's die out on current conventional computing?
serious_quantum 2 years ago prev next
On the positive side, quantum computing has great potential in drug discovery, material science, data analytics and optimization problems.

I would love to hear real-world practical implementations of quantum computing. Any examples in financial modeling or trading?

What is the practical timeline for industrial use of quantum computers, say, 2030 or 2050?
opinionated 2 years ago next
I think 2040 is at best optimistic for well established, widespread quantum computing adoption.

Quantum Machine Learning is a subfield that will explosively gain traction. There are applications for search engines and autoencoders in this.

But QML is not expected to replace traditional machine learning anytime soon, right?

There are so many opportunities to explore, but we also need to be auditing the claims of many
