is there any different technology like blockchain but it should be resistant to quantum computing, means better then todays blockchain technology. which cannot be hacked or attacked by quantum computers,
but also ensures efficient transaction processing(like todays blockchain technology) and scalability?

Blockchain and quantum resistance have nothing to do with one another. Specific algorithms/cryptographic protocols are either quantum resistant or not. You don't need a different technology than blockchain to be quantum resistant. Bitcoin may need to make a quantum resistant update at some point, or it may not, but it doesn't need something other than blockchain.
In terms of efficient transacting - that's what L2 is for.
So the answer is no, there is no need for some other technology besides blockchain.
