Can photonic qubits actually work at room temperature or is that just speculation?

[CyberRider56]

Stanford and Monash reported room-temperature quantum devices with light. Is this proven working or early-stage lab experiment that might not scale?

[Ben]

It's proven working in lab but at tiny scale. Single devices working is different from thousand-qubit system. Lab scale doesn't mean manufacturable scale

[Arty Candle]

The physics works. You can make photonic devices without extreme cooling. That's real advance. Whether this scales to practical quantum computer unknown

[StuckOnDestiny]

Room temperature is huge advantage if it works. Eliminates dilution refrigerator bottleneck. But room temperature still has noise thermal fluctuations that slow photonic qubits

[TheRock]

Photonic systems have different error modes than superconducting. Lower coherence times require different approach to error correction. Unknown if that scales easily

[Depot76]

The proof of principle is valuable. It shows different path exists. Doesn't prove it's faster than current approaches. But opens research direction

[Leo]

Integration is challenge. Making quantum gates work at room temperature is harder than at cryogenic. Photonic systems need precise control. Noise at room temperature makes precision harder

[Terry_33]

Long-term this is probably important. Room-temperature quantum devices might be where field heads eventually. But 5-10 year path to practical systems

[Warden]

Current quantum computers use extreme temperatures because it works. Transitioning to room temperature will take major breakthroughs. Announcements make it sound inevitable it's not

[GlassKnight]

The Stanford and Monash results are real but incremental. They show it's possible. Doesn't show it's practical or competitive

[Sequence48]

This is why multiple approaches are wise bet. Some scale superconducting to useful levels. Others find way to scale photonic. Whichever works first wins
