According to the book Atomic Adventures by James Mahaffey, that project has been underway for several years now. The application is more focused on instant communications from very long distances across the universe.

What Star Trek calls “Sub-Space Communications”..............

-How many times can a photon be split into photons?

The energy of the daughter photosn is half the starting photon so even there’s no fundamental cap on the number of splitting events the practical energy of the split is a factor in making the split or knowing you have split the later generations of daughter photons.

Get back to me when it’s a torpedo.

I’d be quite happy with my personal phaser.

Found? The answer to why when someone says “knock knock” we automatically reply “who is there”

This sounds phake to me.

Speaking of sound, can they split sound waves? If a tree falls in the woods and there are two microphones, do the waves split and conserve angular momentum? How about Christina Agular momentum?

That a photon has angular momentum at all is one of the strangest things the mind can contemplate.

“The application is more focused on instant communications from very long distances across the universe.”

Information cannot exceed the speed of light in a vacuum.

Me too. They would really solve the problem of body disposal.

You split a photon you get two photons................

"I don’t know why they haven’t used this ‘entangling’ for a super secure communications system yet.................."

They have, it's just not built into existing devices yet (routers, firewalls, etc.). Right now it requires external servers for key exchange. Look up "QKD" (Quantum Key Distribution) for more info.

Just glad they did this to a single photon rather than to a married photon.

IANA physicist, obviously.

How do you split a photon? What "blade" do you use?

When you split a photon, what do you get? Smaller photons? How many? Why two, not three, or a thousand?

Can you reassemble the pieces, I.E. build photons out of smaller photons? Do you need glue?

Photons are units of light. When you split a photon, do you get more light, or less? In what spectrum? Visible, IR, UV, what?

Just great one more thing to drag around.

If’n a photon splits it becomes a banana split.
