Some are thinking maybe 10 years away until Quantum matures enough to be able to crack current encryption methods. Industry is working towards 5 years to have the hardware capability available.
The idea of day 0 approaching when secrets are no more has some concerns in how that is going to play out. New quantum encryption methods will cover the gap for those at the top of the game.
The first lecture of my maths degree was a stern warning never to research mass prime factorisation or Shor's algorithm (the equation that cracks all encrypyion once quantum computing gets over the interference/decoherence issue) as the weapons systems of every military in the world would be launched on the first people to get close to implementing it at day0.
Since then a few militaries and banking systems have switched to encryptiion methods that are resistant/impervious to quantum snooping and major banking systems are meant to have similar.
I did a proof of concept paper on making a simple DIY post day0 encryption method 15 - 20 years ago using a length of fibre optic and a green and red laser as due to wavelength properties of different colours it's easy to sandwich the protected info in an event horizon/black hole that prevents any data leaak and any attempt to intercept the data would cause the data to corrupt/decohere and be easily detectable.
I think the more advanced methods are based on a similar process but crossed with one time encryption have coloured filters at entry and exit points to further protect the data from intrusion as there's billions of permutations and combinations and attacker would have to with perform per second with 100% accuracy to avoid the data scrambling.
China did a major breakthrough in quantum computing a couple of months back that massively decreased the ammoutn of decoherence/error in quantum computing but I'd be suprised if qc is capable of producing reliable results or scaled up from 100s to 1,000,000+ qbits required to run shor's algorithm in the next 25 years without major physics/material science breakthoughs.
