IONQ LETTER TO STOCKHOLDERS

 Letter to Stockholders - IONQ

  1. Will IonQ, and quantum computing in general, achieve quantum supremacy?

  2. No. There are fundamental reasons why this is not going to happen.

  3. When will the quantum market take off?

  4. Never. Don't invest in it.

  5. Why does IonQ use trapped ion qubits in its quantum systems?

  6. Whatever you pick, the outcome is very much the same junk.

  7. What does IonQ think of other announced breakthroughs in quantum?

  8. Breakthroughs in quantum computing show up all the time. Then, they go away.

  9. Do trapped ion systems have a path to scale?

  10. No, actually, they don't have any.

  11. Are trapped ions fast enough to tackle large applications in the future?

  12. Ion-trapped quantum computers are as slow as molasses in February.

  13. Will IonQ win in the quantum computing market?

  14. Check IONQ quarterly financials: revenue 6.1M, net income -41.9M.

To find () and (), we need to solve the functional equation ((+))=()+().

Let's denote () as for simplicity:

((+))=()+()

Now, let's consider some particular values of and to simplify the equation:

  1. Let ==0: ((0))=(0)+(0) ((0))=2(0)

  2. Let =0: (())=()+(0)

  3. Let =0: (())=(0)+()

Now, let's compare the equations from 2 and 3:

()+(0)=(0)+()

This implies that (0) is a constant, let's denote it as . Therefore:

()+=+() ()=

So, ()= for all real values of .

Therefore, () and () are both constant functions, and the value of () and () is the same for any real numbers and .
