Quantum bitcoin - qBitcoin - online quantum cash

A decentralized online quantum cash system, called qBitcoin, is given. Researchers designed a system which has great benefits of quantization in the following sense.A Firstly, quantum teleportation technology is used for coin transaction, which prevents an owner of a coin from keeping the original coin data after sending the coin to another. This was a main problem in systems using classical information and a blockchain was introduced to solve this issue. In qBitcoin, the double-spending problem never happens and its security is guaranteed theoretically by virtue of quantum information theory. Making a bock is time consuming and the system of qBitcoin is based on a quantum chain, instead of blocks. Therefore a payment can be completed much faster than Bitcoin. Moreover they employ quantum digital signature so that it naturally inherits properties of peer-to-peer (P2P) cash system as originally proposed in Bitcoin.

The novelty of qBitcoin compared to Bitcoin or other quantum money schemes can be summarized as follows.
1. Quantum teleportation is used to transmit a coin. This prevents from double spending in a simple way without help of a blockchain.
2. Quantum digital signature is used to verify transaction. This requires other participants to be involved in verifying signatures, hence it is compatible with P2P.
3. Transaction data is stored not in a block but in a point, hence transaction is immediately completed once if signature is verified. In other words, a blockchain is replaced by a quantum chain.

This is nonsense… It's like saying that you can transmit a file by mailing a USB stick, which absolutely guarantees that you, the sender, no longer have the original file. That's wrong—all that mailing a USB stick guarantees is that you don't have the USB stick any more, not that you didn't keep a copy of the contents. Similarly, quantum teleportation eats the input state but says nothing about any other copies of the input state that may exist.

Quantum Bitcoin... sounds good but... it is not Bitcoin... it is just a copy cat...

No offense to the one who posted this but your rank is already Legendary, I think this is not in the proper section as it is an another Altcoin that copied the name of Bitcoin(you just added Quantum to make it attractive)

So this one is using a 'quantum teleportation technology' so what is its security compare to 'blockchain technology' if double spending never happens to it?
because you just explaining what will be the technology not the security itself that is more important more than anything when it comes to transactions.

Making a payment faster doesn't mean it is secured. But good luck with this though I hope it will work just more explanation and please be detailed.
